ABOUT THIS PROSPECTUS

        You should rely only on the information contained in this prospectus. We have not and the underwriters have not, authorized any other person to provide you with information different from that contained in this prospectus. If any person provides you with different or inconsistent information, you should not rely on it. We are offering to sell, and seeking offers to buy, the common stock only in jurisdictions where offers and sales are permitted.

        The information contained in this prospectus is accurate only as of the date of this prospectus, regardless of the time of delivery of this prospectus or of any sale of our common stock. Our business, financial condition, results of operations and prospects may have changed since that date.

MARKET AND INDUSTRY DATA

        This prospectus contains market and industry data, primarily from reports published by America's Commercial Transportation Publications, or ACT, the American Trucking Association, or ATA, and from internal company surveys, studies and research related to the truck components industry and its segments as well as the truck industry in general. These data include estimates and forecasts regarding future growth in these industries, truck freight growth and the historical average age of active U.S. heavy-duty trucks. Such data have been published in industry publications that typically indicate that they have derived the data from sources believed to be reasonable, but do not guarantee the accuracy or completeness of the data. While we believe these industry publications to be reliable, we have not independently verified the data or any of the assumptions on which the estimates and forecasts are based. Similarly, internal company surveys, studies and research, while believed by us to be reliable, have not been verified by any independent sources.

SUMMARY HISTORICAL AND PRO FORMA AS ADJUSTED
CONSOLIDATED FINANCIAL AND OTHER DATA

        Set forth below is summary consolidated financial and other data of Accuride and TTI and pro forma as adjusted financial and other data of Accuride at the dates and for the periods indicated. We derived the statements of operations data for the years ended December 31, 2000, 2001, 2002, 2003 and 2004 and consolidated balance sheet data as of December 31, 2000, 2001, 2002, 2003 and 2004, from Accuride's audited financial statements.

These rules require that the weighted average share calculation give retroactive effect to any changes in our capital structure as well as the number of shares whose sale proceeds will be used to repay any debt as reflected in the pro forma adjustments.

(g)

Represents current assets less cash and current liabilities, excluding debt.

(h)

EBITDA is not intended to represent cash flows as defined by generally accepted accounting principles, or GAAP, and should not be considered as an alternative to net income as an indicator of our operating performance or to cash flows as a measure of liquidity. We have included information concerning EBITDA because it is a basis upon which we assess our financial performance and incentive compensation, and certain covenants in our borrowing arrangements are tied to this measure. In addition, EBITDA is used by certain investors as a measure of the ability of a company to service or incur indebtedness and because it is a financial measure commonly used in our industry. EBITDA as presented in this prospectus may not be comparable to similarly titled measures used by other companies in our industry. EBITDA consists of our net income (loss) before interest expense, income tax (expense) benefit, depreciation and amortization. Set forth below is a reconciliation of our net income (loss) to EBITDA:

(i)

Net income (loss) was affected by the unusual items presented in the following table:

(1)

(2)

In the quarter ended June 30, 2004, TTI entered into negotiations with a buyer for the sale of certain of its assets held for sale at its Erie, Pennsylvania location at a price below carrying value. To comply with the requirements of SFAS

11

No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," TTI recorded an impairment loss of $2.2 million.

(3)

In August 2004, TTI recorded severance expense of $3.5 million in connection with the retirement of its former chief executive officer.



(4)

Transaction related costs include $2.9 million of TTI's expenses related to the aborted initial public offering in 2004, and $1.0 million of expenses related to the merger in 2004.



(5)

Restructuring and integration costs for 2000 included $5.4 million of restructuring and integration costs related to operations in Monterrey, Mexico and $0.6 million for restructuring costs in the United States. Restructuring and integration costs for 2001 include $2.7 million of charges related to the closure of the Columbia, Tennessee facility and $1.6 million of restructuring charges related to our other facilities. Restructuring and integration costs for 2002 included $1.2 million of costs related to a reduction in the employee workforce and $1.1 million of costs related to the consolidation of light wheel production.



(6)

In 2000, we incurred $3.1 million of costs related to aborted merger and acquisition activities.



(7)

Business interruption costs for 2003 included $2.2 million of cost associated with the fire damage and resulting business interruption sustained at our facility in Cuyahoga Falls, Ohio in August 2003. Business interruption costs for 2004 included $1.2 million for costs associated with roof damage and resulting business interruption sustained at Accuride's facility in Cuyahoga Falls, Ohio and $0.5 million of additional costs associated with the fire damage and resulting business interruption sustained at Accuride's facility in Cuyahoga Falls, Ohio in August 2003. These costs were offset by insurance proceeds in the amount of $2.0 million related to our business interruption claim for the 2003 fire.



(8)

In 2003, we incurred $0.4 million for strike contingency costs associated with the renewal of our labor contract at our facility in Erie, Pennsylvania.



(9)

Other unusual items in 2001 included $0.2 million of charges related to the amended and restated credit agreement entered into on July 27, 2001. Other unusual items in 2002 included $0.4 million of costs related to non-cash pension curtailment expenses associated with a labor dispute at our Henderson, Kentucky facility, $1.3 million one-time settlement fee paid to prior owner, $0.5 million of aborted business development costs and $0.4 million of other non-recurring professional fees related to a corporate restructuring at our Mexican subsidiary. Other unusual items in 2003 included $0.3 million for pension-related costs at our facility in London, Ontario.



(10)

Items related to our credit agreement refers to amounts utilized in the calculation of financial convenants in Accuride's senior debt facility. Items related to our credit agreement in 2000 consist of foreign currency losses of $6.2 million. Items related to our credit agreement in 2001 consisted of foreign currency losses of $6.2 million and other expense of $3.6 million. Items related to our credit agreement in 2002 consisted of foreign currency losses of $1.6 million and other income of $3.1 million. Items related to our credit agreement in 2003 consisted of foreign currency gains of $0.9 million and other expense of $0.1 million. Items related to our credit agreement for the year ended December 31, 2004 included currency gain and other income of $0.1 million.



(11)

Cost of sales on a pro forma basis included $2.1 million to reflect the sale of inventory that has been adjusted to fair market value as part of the TTI merger.

(j)

Effective January 1, 2002, Accuride adopted Statement of Financial Accounting Standard, or SFAS, No. 142, "Accounting for Goodwill and Other Intangible Assets." No goodwill amortization was recorded during the years ended December 31, 2002, 2003 and 2004.

12

(a)

In March 2000, TTI was recapitalized in a transaction in which approximately 88% of the fully diluted shares of TTI's common stock was converted into the right to receive $21.50 per share in cash. In connection with this recapitalization, TTI entered into new debt financing arrangements.

(b)

During 2002, as a result of TTI's adoption of SFAS No. 142, TTI recorded a transitional goodwill impairment charge net of taxes of $3.8 million. See Note 5 to TTI's audited consolidated financial statements included elsewhere in this prospectus.

(c)

Represents current assets less cash and current liabilities, excluding debt.

(d)

EBITDA is a non-GAAP financial measure and is defined as net income (loss) before discontinued operations and the cumulative effect of accounting changes plus (1) depreciation and amortization, (2) interest expense, net of interest income, (3) loss on debt extinguishment and (4) income taxes. TTI relies on EBITDA as the primary measure to review and assess its operating performance and its management teams. Management and investors also review EBITDA to evaluate TTI's overall performance and to compare TTI's current operating results with corresponding periods and with other companies in the truck components industry. We believe that it is important and useful to investors to provide disclosure of TTI's operating results on the same basis as that used by TTI's management. TTI also believes that it can assist investors in comparing its performance to that of other companies on a consistent basis without regard to items that may not exist or do not directly affect its operating performance. You should not consider EBITDA in isolation or as a substitute for net income or cash flow from operations or other cash flow statement data determined in accordance with GAAP. In addition, because EBITDA is not a measure of financial performance under GAAP and is susceptible to varying calculations, the EBITDA measure presented here may differ from and may not be comparable to similarly titled measures used by other companies.

13

Set

forth below is a reconciliation of TTI's net income (loss) to EBITDA:

(e)

TTI's net income (loss) was affected by the following unusual items:

(1)

Selling, general and administrative expenses included $4.1 million of non-cash compensation in 2000 relating to the recapitalization of TTI (by way of a going-private transaction) in March of that year, $0.3 million for management bonuses related to the exchange of subordinated debt for preferred stock in December 2003 and $0.4 million in 2004, related to professional fees primarily for the 2001 audit performed in connection with TTI's proposed initial public offering.



(2)

In 2000, TTI recorded $0.6 million of restructuring costs related to the closure of its Fort Worth, Texas plating facility. In 2001, TTI recorded $19.6 million of restructuring costs, which included $18.9 million of non-cash fixed asset impairment charges and $0.7 million of employee separation expenses. The costs related primarily to the closure of TTI's Erie, Pennsylvania iron casting and machining operation.



(3)

In early 2003, TTI undertook a review, with assistance from third-party specialists, of its environmental exposures. The review indicated that there was a substantial reduction in TTI's probable exposure at identified sites due primarily to the inactive status or closure of many of the sites and consent decrees obtained at certain of the sites. Accordingly, TTI reduced its reserves relating to the sites by $6.6 million.



(4)

On October 30, 2003, TTI sold the real property of its Emeryville, California plant for $6.5 million and moved the operations into a leased facility in the area. The transaction resulted in a net gain of $3.7 million. This $3.7 million gain was offset by losses on dispositions of fixed assets of $1.1 million. In the quarter ended June 30, 2004, TTI entered into negotiations with a buyer for the sale of certain of its assets held for sale at its Erie, Pennsylvania location at a price below carrying value. To comply with the requirements of SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," TTI recorded an impairment loss of $2.2 million.



(5)

In August of 2004, TTI recorded severance expense of $3.5 million in connection with the retirement of its former chief executive officer.



(6)

TTI recorded gains from the sale of its residual ownership interest in its former rail car business of $5.0 million in 2001 and $10.0 million in 2003.



(7)

Transaction related costs include $14.3 million related to underwriting expenses in 2000, $1.6 million related to the issuance of $10.0 million in common stock and modification of TTI's borrowing agreements in 2001, $2.9 million of expenses related to the aborted initial public offering in 2004 and $1.0 million of expenses related to the TTI merger in 2004.

RISK FACTORS

         You should carefully consider the following factors, in addition to other information included in this prospectus, before investing in our common stock. If any of these risks actually occurs, our business, financial condition or results of operations will likely suffer. In that event, the trading price of our common stock could decline, and you may lose all or part of your investment.

Risks Related to Our Business and Industry

We are dependent on sales to a small number of our major customers and on our status as standard supplier on certain truck platforms of each of our major customers.

        Sales, including aftermarket sales, to Freightliner, PACCAR, International and Volvo/Mack constituted approximately 16%, 15%, 15% and 10%, respectively, of our 2004 pro forma net sales. No other customer accounted for more than 8% of our pro forma net sales during this period. The loss of any significant portion of sales to any of our major customers could have a material adverse effect on our business, results of operations or financial condition.

        We are a standard supplier on a majority of truck platforms at each of our major customers, which results in recurring revenue as our standard components are installed on most trucks ordered from that platform, unless the end user specifically requests a different product, generally at an additional charge. The selection of one of our products as a standard component may also create a steady demand for that product in the aftermarket. We may not maintain our current standard supplier positions in the future, and may not become the standard supplier for additional truck platforms. The loss of a significant standard supplier position or a significant number of standard supplier positions with a major customer could have a material adverse effect on our business, results of operations or financial condition.

        We are continuing to engage in efforts intended to improve and expand our relations with each of Freightliner, PACCAR, International and Volvo/Mack. We have supported our position with these customers through direct and active contact with end users, trucking fleets and dealers, and have located certain of our sales personnel in offices near these customers and most of our other major customers. We cannot assure you that we will maintain or improve our customer relationships, whether these customers will continue to do business with us as they have in the past or whether we will be able to supply these customers or any of our other customers at current levels. The loss of a significant portion of our sales to Freightliner, PACCAR, International or Volvo/Mack could have a material adverse effect on our business, results of operations or financial condition. In addition, the delay or cancellation of material orders from, or problems at, Freightliner, PACCAR, International or Volvo/Mack or any of our other major customers could have a material adverse effect on our business, results of operations or financial condition.

Increased cost of raw materials and purchased components may adversely affect our business, results of operations or financial condition.

        Our business is subject to the risk of price increases and fluctuations and periodic delays in the delivery of raw materials and purchased components that are beyond our control. Our operations require substantial amounts of raw steel, aluminum, steel scrap, pig iron, electricity, coke, natural gas, sheet and formed steel, bearings, purchased components, fasteners, foam, fabrics, silicon sand, binders, sand additives, coated sand and tube steel. Fluctuations in the delivery of these materials may be driven by the supply/demand relationship for a material, factors particular to that material or governmental regulation for raw materials such as electricity and natural gas. In addition, if any of our suppliers seeks bankruptcy relief or otherwise cannot continue its business as anticipated or we cannot renew our supply contracts on favorable terms, the availability or price of raw materials could be adversely affected. Fluctuations in prices and/or availability of the raw materials or purchased components used

15

by us, which at times may be more pronounced during periods of higher truck builds, may affect our profitability and, as a result, have a material adverse effect on our business, results of operations or financial condition.

        We use substantial amounts of raw steel and aluminum to produce wheels and rims. Although raw steel is generally available from a number of sources, we have obtained favorable sourcing by negotiating and entering into high-volume contracts with third parties with terms ranging from one to three years. We obtain raw steel and aluminum from various third-party suppliers. We cannot assure you that we will be successful in renewing our supply contracts on favorable terms or at all. A substantial interruption in the supply of raw steel or aluminum or inability to obtain a supply of raw steel or aluminum on commercially desirable terms could have an adverse effect on our business, results of operations or financial condition. We are not always able, and may not be able in the future, to pass on increases in the price of raw steel or aluminum to our customers. In particular, when raw material prices increase rapidly or to significantly higher than normal levels, we may not be able to pass price increases through to our customers on a timely basis, if at all, which could adversely affect our operating margins and cash flow. Any fluctuations in the price or availability of raw steel or aluminum may have a material adverse effect on our business, results of operations or financial condition.

        Steel scrap and pig iron are also major raw materials used in our business to produce our wheel-end and industrial components. Steel scrap is derived from, among other sources, junked automobiles, industrial scrap, railroad cars, agricultural and heavy machinery and demolition steel scrap from obsolete structures, containers and machines. Pig iron is a low-grade cast iron which is a product of smelting iron ore with coke and limestone in a blast furnace. The availability and price of steel scrap and pig iron are subject to market forces largely beyond our control, including North American and international demand for steel scrap and pig iron, freight costs, speculation and foreign exchange rates. Steel scrap and pig iron availability and price may also be subject to governmental regulation. We are not always able, and may not be able in the future, to pass on increases in the price of steel scrap and pig iron to our customers. In particular, when raw material prices increase rapidly or to significantly higher than normal levels, we may not be able to pass price increases through to our customers on a timely basis, if at all, which could adversely affect our operating margins and cash flow. Any fluctuations in the price or availability of steel scrap or pig iron may have a material adverse effect on our business, results of operations or financial condition. See "Business—Raw Materials and Suppliers."

Our business is affected by the cyclical nature of the industries and markets that we serve.

        The heavy- and medium-duty truck and truck components industries, the heavy-duty truck OEM market and, to a lesser extent, the medium-duty truck OEM market and the heavy- and medium-wheel and light-wheel industries are highly cyclical. These industries and markets fluctuate in response to factors that are beyond our control, such as general economic conditions, interest rates, federal and state regulations, consumer spending, fuel costs and our customers' inventory levels and production rates. These industries and markets are particularly sensitive to the industrial sector of the economy, which generates a significant portion of the freight tonnage hauled by trucks. Economic downturns in the industries or markets that we serve generally result in reduced sales of our products, which could lower our profits and cash flows. In addition, our operations are typically seasonal as a result of regular customer maintenance and model changeover shutdowns, which typically occur in the third and fourth quarter of each calendar year. This seasonality may result in decreased net sales and profitability during the third and fourth fiscal quarters of each calendar year. Weakness in overall economic conditions or in the markets that we serve, or significant reductions by our customers in their inventory levels or future production rates, could result in decreased demand for our products and could have a material adverse effect on our business, results of operations or financial condition.

16

Cost reduction and quality improvement initiatives by OEMs could have a material adverse effect on our business, results of operations or financial condition.

        We are primarily a components supplier to the heavy- and medium-duty truck industries, which are characterized by a small number of OEMs that are able to exert considerable pressure on components suppliers to reduce costs, improve quality and provide additional design and engineering capabilities. Given the fragmented nature of the industry, OEMs continue to demand and receive price reductions and measurable increases in quality through their use of competitive selection processes, rating programs and various other arrangements. We may be unable to generate sufficient production cost savings in the future to offset such price reductions. OEMs may also seek to save costs by relocating production to countries with lower cost structures, which could in turn lead them to purchase components from local suppliers with lower production costs. Additionally, OEMs have generally required component suppliers to provide more design engineering input at earlier stages of the product development process, the costs of which have, in some cases, been absorbed by the suppliers. Future price reductions, increased quality standards and additional engineering capabilities required by OEMs may reduce our profitability and have a material adverse effect on our business, results of operations or financial condition.

We may be unable to integrate TTI and other acquired companies successfully.

        Integrating TTI and any future acquired business requires substantial management, financial and other resources and may pose risks with respect to customer service and market share. Furthermore, integrating TTI or any business acquired in the future involves a number of special risks, some or all of which could have a material adverse effect on our business, results of operations or financial condition. These risks include:

•

unforeseen operating difficulties and expenditures associated with managing a substantially larger, broader and more geographically diverse organization;



•

difficulties in assimilating acquired personnel, operations and technologies;



•

challenges in implementing appropriate systems, policies, benefits and compliance programs;



•

impairment of goodwill and other intangible assets;



•

diversion of management's attention from ongoing development of our business or other business concerns;



•

potential loss of customers;



•

failure to retain key personnel of the acquired businesses;



•

the use of substantial amounts of our available cash; and



•

the incurrence of additional indebtedness.

        Any one or a combination of these factors may cause our revenues or earnings to decline and we cannot assure you that we will be able to maintain or enhance the profitability of TTI or any acquired business or consolidate its operations to achieve cost savings.

        In addition, there may be liabilities that we fail, or are unable, to discover in the course of performing due diligence investigations on each company or business we have already acquired or may acquire in the future. Such liabilities could include those arising from employee benefits contribution obligations of a prior owner or non-compliance with applicable federal, state or local environmental requirements by prior owners for which we, as a successor owner, may be responsible. We cannot assure you that rights to indemnification by sellers of assets to us, even if obtained, will be enforceable, collectible or sufficient in amount, scope or duration to fully offset the possible liabilities associated

17

with the business or property acquired. Any such liabilities, individually or in the aggregate, could have a material averse effect on our business, results of operations or financial condition.

As a result of the TTI merger, we are a substantially larger and broader organization, and if our management is unable to manage the larger organization, our operating results will suffer.

        As a result of the TTI merger, our workforce increased from approximately 1,800 employees to over 4,700 employees based at 17 facilities in North America and we do not presently anticipate any layoffs in connection with the TTI merger. We will face challenges inherent in efficiently managing an increased number of employees over large geographic distances, including the need to implement appropriate systems, policies, benefits and compliance programs. The inability to successfully manage the substantially larger organization, or any significant delay in achieving successful management, could have a material adverse effect on our business, results of operations or financial position.

TTI's independent auditors have indicated to us that in connection with their audit of TTI's financial statements they believe there were material weaknesses in TTI's internal controls for the year ended December 31, 2004. Our failure to implement and maintain effective internal controls in our business could have a material adverse effect on our business, financial condition and stock price.

        In connection with the completion of its audit of, and the issuance of an unqualified report on, TTI's financial statements for the year ended December 31, 2004, our independent registered public accounting firm, Deloitte & Touche LLP, identified deficiencies involving internal controls of TTI that it considers to be reportable conditions that constitute material weaknesses pursuant to standards established by the American Institute of Certified Public Accountants. The material weaknesses noted include: (1) weaknesses related to field level controls at TTI's Gunite and Brillion locations, which demonstrated local managements' lack of consistent understanding and compliance with TTI's policies and procedures and which included errors that resulted in certain book to physical inventory adjustments; and (2) a weakness related to the corporate level financial reporting, which consisted of the failure to adequately review the work of a third party actuarial consultant requiring an adjustment to our workers' compensation liability. For a further description of the nature of the material weaknesses and the Company's remediation efforts, see "Business—Internal Control over Financial Reporting."

        In response to the material weaknesses identified by Deloitte & Touche LLP with respect to TTI's internal control over financial reporting, management is implementing additional procedures and controls to remediate the material weaknesses. Actions being taken by management to remediate the material weaknesses with respect to TTI include: (i) monitor compliance with TTI's policies and procedures at the operating locations; (ii) develop targeted site reviews for locations that possess the weakest records of complying with TTI's policies and procedures; and (iii) review all assumptions and data provided to TTI by third party service providers. However, if not properly implemented, these measures may not completely eliminate the material weaknesses identified. The existence of one or more material weaknesses or reportable conditions could result in errors in or restatements of our financial statements and inhibit the Company's ability to produce reliable financial reports, which may cause investors to lose confidence in the Company's reported financial information and have a material adverse effect on the Company's business and stock price.

We operate in highly competitive markets.

        The markets in which we operate are highly competitive. We compete with a number of other manufacturers and distributors that produce and sell similar products. Our products primarily compete on the basis of price, manufacturing and distribution capability, product design, product quality, product delivery and product service. Some of our competitors are companies, or divisions, units or subsidiaries of companies, that are larger and have greater financial and other resources than we do.

18

Our products may not be able to compete successfully with the products of our competitors. In addition, our competitors may foresee the course of market development more accurately than we do, develop products that are superior to our products, have the ability to produce similar products at a lower cost than we can or adapt more quickly than we do to new technologies or evolving regulatory, industry or customer requirements. As a result, our products may not be able to compete successfully with their products. In addition, OEMs may expand their internal production of wheels, shift sourcing to other suppliers or take other actions that could reduce the market for our products and have a negative impact on our business. We may encounter increased competition in the future from existing competitors or new competitors. We expect these competitive pressures in our markets to remain strong. See "Business—Competition."

        In addition, potential competition from foreign truck components suppliers, especially in the aftermarket, may lead to an increase in truck components imports into North America, adversely affecting our market share and negatively affecting our ability to compete. Foreign truck components suppliers may in the future increase their currently modest share of the markets for truck components in which we compete. Some of these foreign suppliers may be owned, controlled or subsidized by their governments, and their decisions with respect to production, sales and exports may be influenced more by political and economic policy considerations than by prevailing market conditions. In addition, foreign truck components suppliers may be subject to less restrictive regulatory and environmental regimes that could provide them with a cost advantage relative to North American suppliers. Therefore, there is a risk that some foreign suppliers may increase their sales of truck components in North American markets despite decreasing profit margins or losses. If future trade cases do not provide relief from such potential trade practices, U.S. protective trade laws are weakened or international demand for trucks and/or truck components decreases, an increase of truck component imports into the United States may occur, which could have a material adverse effect on our business, results of operations or financial condition.

We face exposure to foreign exchange rate fluctuations and if we were to experience a substantial fluctuation, our profitability may change.

        In the normal course of doing business, we are exposed to risks associated with changes in foreign exchange rates, particularly with respect to the Canadian dollar. We use forward foreign exchange contracts, and other derivative instruments designated as hedging instruments under SFAS No. 133, to offset the impact of the variability in exchange rates on our operations, cash flows, assets and liabilities. At December 31, 2004, we had open foreign exchange forward contracts of $24.8 million. Factors that could further impact the risks associated with changes in foreign exchange rates include the accuracy of our sales estimates, volatility of currency markets and the cost and availability of derivative instruments. For example, during 2004, we experienced an 8.2% adverse change in the Canadian dollar. This resulted in a $10.2 million adverse impact on our 2004 earnings before taxes. This quantification of exposure to the market risk does not take into account the $4.2 million offsetting impact of derivative instruments. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Foreign Currency Risk."

We may not be able to continue to meet our customers' demands for our products and services.

        We must continue to meet our customers' demand for our products and services. However, we may not be successful in doing so. If our customers' demand for our products and/or services exceeds our ability to meet that demand, we may be unable to continue to provide our customers with the products and/or services they require to meet their business needs. Factors that could result in our inability to meet customer demands include an unforeseen spike in demand for our products and/or services, a failure by one or more of our suppliers to supply us with the raw materials and other resources that we need to operate our business effectively or poor management of our company or one or more divisions

19

or units of our company, among other factors. Our ability to provide our customers with products and services in a reliable and timely manner, in the quantity and quality desired and with a high level of customer service, may be severely diminished as a result. If this happens, we may lose some or all of our customers to one or more of our competitors, which would have a material adverse effect on our business, results of operations or financial condition.

        In addition, it is important that we continue to meet our customers' demands in the truck components industry for product innovation, improvement and enhancement, including the continued development of new-generation products, design improvements and innovations that improve the quality and efficiency of our products. Developing product innovations for the truck components industry has been and will continue to be a significant part of our strategy. However, such development will require us to continue to invest in research and development and sales and marketing. In the future, we may not have sufficient resources to make such necessary investments, or we may be unable to make the technological advances necessary to carry out product innovations sufficient to meet our customers' demands. We are also subject to the risks generally associated with product development, including lack of market acceptance, delays in product development and failure of products to operate properly. We may, as a result of these factors, be unable to meaningfully focus on product innovation as a strategy and may therefore be unable to meet our customers' demand for product innovation.

Equipment failures, delays in deliveries or catastrophic loss at any of our facilities could lead to production or service curtailments or shutdowns.

        We manufacture our products at 17 facilities and provide logistical services at six just-in-time sequencing facilities in the United States. An interruption in production or service capabilities at any of these facilities as a result of equipment failure or other reasons could result in our inability to produce our products, which would reduce our net sales and earnings for the affected period. In the event of a stoppage in production at any of our facilities, even if only temporary, or if we experience delays as a result of events that are beyond our control, delivery times to our customers could be severely affected. Any significant delay in deliveries to our customers could lead to increased returns or cancellations and cause us to lose future sales. Our facilities are also subject to the risk of catastrophic loss due to unanticipated events such as fires, explosions or violent weather conditions. We may experience plant shutdowns or periods of reduced production as a result of equipment failure, delays in deliveries or catastrophic loss, which could have a material adverse effect on our business, results of operations or financial condition.

We may incur potential product liability, warranty and product recall costs.

        We are subject to the risk of exposure to product liability, warranty and product recall claims in the event any of our products results in property damage, personal injury or death, or does not conform to specifications. We may not be able to continue to maintain suitable and adequate insurance in excess of our self-insured amounts on acceptable terms that will provide adequate protection against potential liabilities. In addition, if any of our products proves to be defective, we may be required to participate in a recall involving such products. A successful claim brought against us in excess of available insurance coverage, if any, or a requirement to participate in any product recall, could have a material adverse effect on our business, results of operations or financial condition.

Work stoppages or other labor issues at our facilities or at our customers' facilities could adversely affect our operations.

        On a pro forma basis, as of December 31, 2004, approximately 48% of our workforce was represented by unions. As a result, we are subject to the risk of work stoppages and other labor relations matters. Any prolonged work stoppage or strike at any one of our principal unionized facilities could have a material adverse effect on our business, results of operations or financial

20

condition. In addition, certain of our facilities have separate agreements covering the workers at each such facility and, as a result, we have collective bargaining agreements with several different unions. These collective bargaining agreements expire at various times over the next few years, with no contract expiring before April 2005, with the exception of our union contract with our hourly employees at our Monterrey, Mexico facility, which is renewed on an annual basis. Negotiations to renew our union contract with the United Auto Workers covering hourly employees at our Rockford, Illinois facility, which expires in April 2005, began on March 30, 2005. Any failure by us to reach a new agreement upon expiration of such union contracts may have a material adverse effect on our business, results of operations or financial condition. In June 2004, certain employees at our Cuyahoga Falls, Ohio facility elected to be represented by United Auto Workers. The initial contract is currently under negotiation and we do not anticipate that the unionization of the employees at our Cuyahoga Falls, Ohio facility will have an adverse effect on our operating costs. See "Business—Employees and Labor Unions."

        In addition, if any of our customers experiences a material work stoppage, that customer may halt or limit the purchase of our products. This could cause us to shut down production facilities relating to these products, which could have a material adverse effect on our business, results of operations or financial condition.

We are subject to a number of environmental rules and regulations that may require us to make substantial expenditures.

        Our operations, facilities and properties are subject to extensive and evolving laws and regulations pertaining to air emissions, wastewater discharges, the handling and disposal of solid and hazardous materials and wastes, the investigation and remediation of contamination, and otherwise relating to health, safety and the protection of the environment and natural resources. As a result, we are involved from time to time in administrative or legal proceedings relating to environmental, health and safety matters, and have in the past incurred and will continue to incur capital costs and other expenditures relating to such matters. In addition to environmental laws that regulate our subsidiaries' ongoing operations, our subsidiaries are also subject to environmental remediation liability. Under the federal Comprehensive Environmental Response, Compensation, and Liability Act, or CERCLA, and analogous state laws, our subsidiaries may be liable as a result of the release or threatened release of hazardous materials into the environment. Our subsidiaries are currently involved in several matters relating to the investigation and/or remediation of locations where they have arranged for the disposal of foundry and other wastes. Such matters include situations in which we have been named or are believed to be Potentially Responsible Parties under CERCLA or state laws in connection with the contamination of these sites. Additionally, environmental remediation may be required to address soil and groundwater contamination identified at certain facilities.

        As of December 31, 2004, we had an environmental reserve of approximately $2.8 million, related primarily to our foundry operations. This reserve is based on current cost estimates and does not reduce estimated expenditures to net present value, but does take into account the benefit of a contractual indemnity given to us by a prior owner of our wheel-end subsidiary. We cannot assure you, however, that the indemnitor will fulfill its obligations, and the failure to do so could result in future costs that may be material. Any cash expenditures required by us or our subsidiaries to comply with applicable environmental laws and/or to pay for any remediation efforts will not be reduced or otherwise affected by the existence of the environmental reserve. Our environmental reserve may not be adequate to cover our future costs related to the sites associated with the environmental reserve, and any additional costs may have a material adverse effect on our business, results of operations or financial condition. The discovery of additional sites, the modification of existing or the promulgation of new laws or regulations, more vigorous enforcement by regulators, the imposition of joint and several liability under CERCLA or analogous state laws, or other unanticipated events could also result in such a material adverse effect.

21

        As part of an initiative regarding compliance in the foundry industry, the U.S. Environmental Protection Agency, or the EPA, conducted an environmental multimedia inspection at Gunite's Rockford, Illinois plant in September and October 2003. Gunite received an administrative complaint from the EPA in January 2005 regarding alleged violations of certain registration and record maintenance regulations, with a proposed penalty in the amount of approximately $138,600. Gunite is reviewing the complaint and has not yet responded.

        The final Iron and Steel Foundry National Emission Standard for Hazardous Air Pollutants, or NESHAP, was developed pursuant to Section 112(d) of the Clean Air Act and requires all major sources of hazardous air pollutants to install controls representative of maximum achievable control technology. We are evaluating the applicability of the Iron and Steel Foundry NESHAP to our foundry operations. If applicable, compliance with the Iron and Steel Foundry NESHAP may result in future significant capital costs, which we currently expect to be approximately $5 million in total during the period 2005 through 2007. See "Business—Environmental Matters."

We might fail to adequately protect our intellectual property, or third parties might assert that our technologies infringe on their intellectual property.

        The protection of our intellectual property is important to our business. We rely on a combination of trademarks, copyrights, patents and trade secrets to provide protection in this regard, but this protection might be inadequate. For example, our pending or future trademark, copyright and patent applications might not be approved or, if allowed, they might not be of sufficient strength or scope. Conversely, third parties might assert that our technologies or other intellectual property infringe on their proprietary rights. Although we have not had litigation with respect to such matters in the past, litigation, which could result in substantial costs and diversion of our efforts, might be necessary, and whether or not we are ultimately successful, the litigation could adversely affect our business, results of operations or financial condition. See "Business—Intellectual Property."

Litigation against us could be costly and time consuming to defend.

        We are regularly subject to legal proceedings and claims that arise in the ordinary course of business, such as workers' compensation claims, OSHA investigations, employment disputes, unfair labor practice charges, customer and supplier disputes and product liability claims arising out of the conduct of our business. Litigation may result in substantial costs and may divert management's attention and resources, which could adversely affect our business, results of operations or financial condition.

If we fail to retain our executive officers, our business could be harmed.

        Our success largely depends on the efforts and abilities of our executive officers, who have collectively been employees of either Accuride or TTI for over 50 years. Their skills, experience and industry contacts significantly benefit us. The loss of any one of them, in particular Mr. Keating, who joined Accuride in December 1996, could have a material adverse effect on our business, results of operations or financial condition. While certain of our executive officers are parties to severance or employment agreements, only Messrs. Weller and Cirar have employment commitments for one year terms. All of our other employees are at will. Our future success will also depend in part upon our continuing ability to attract and retain highly qualified personnel.

Although we do not presently anticipate terminating any senior management employees, certain senior management employees have entered into potentially costly severance arrangements with us.

        Certain of our senior management employees have entered into potentially costly severance arrangements with us. For example, in connection with the TTI merger, we entered into employment

22

agreements with Messrs. Weller, Cirar and Mueller. Mr. Weller's employment agreement provides, among other things, that in the event of the termination of Mr. Weller's employment "without cause" or for "good reason" (as defined therein) at any time prior to August 2, 2007, then Mr. Weller would receive, in addition to certain other benefits, a lump sum payment equal to two times his base salary and the greater of his target bonus under the Accuride annual incentive compensation plan, his target bonus in 2004 from TTI or the average bonus he received for each of 2002, 2003 and 2004 from TTI. Based on his current base salary and his 2004 target TTI bonus, this severance amount would be approximately $1,815,000. Mr. Cirar's employment agreement provides, among other things, that in the event of the termination of Mr. Cirar's employment "without cause" or for "good reason" (as defined therein) at any time prior to August 2, 2007, then Mr. Cirar would receive, in addition to certain other benefits, a lump sum cash payment equal to $1,772,000. Mr. Mueller's employment agreement provides, among other things, that in the event of termination of Mr. Mueller's employment "without Cause" (as defined therein) or Mr. Mueller terminating his employment for any reason on or after April 30, 2005, then Mr. Mueller would receive, in addition to certain other benefits, a lump sum payment of up to $825,000. Additionally, the employment agreements of Messrs. Weller, Cirar and Mueller contain three year post-employment non-compete and non-solicitation provisions of either customers or employees for which Mr. Weller will receive a lump sum payment equal to his base salary and target bonus for the year of his termination and for which Messrs. Cirar and Mueller will receive cash payments of $886,000 and $530,000, respectively. See "Management—Employment Agreements."

        Severance agreements with certain other senior management employees provide that in the event of any such employee's termination "without cause" or for "good reason" (as defined therein) we will pay such employee one year's base salary. As of December 31, 2004, in the event we terminated Mr. Keating, Mr. Murphy, Mr. Armstrong, Ms. Hamme or Mr. Taylor, we would have to make cash payments of $365,137, $296,480, $209,885, $187,355 and $177,850, respectively. See "Management—Severance Agreements."

        In addition, we have entered into change in control agreements with certain senior management employees, including, Mr. Keating, Mr. Murphy, Mr. Armstrong, Ms. Hamme and Mr. Taylor that provide for significant severance payments in the event such employee's employment with us is terminated within 18 months of a change in control or partial change in control (each as defined in the agreement) either by the employee for good reason or by us for any reason other than cause, disability, normal retirement or death. A change in control under these agreements includes any transaction or series of related transactions as a result of which at least a majority of our voting power is not held, directly or indirectly, by the persons or entities who held our securities with voting power before such transactions and KKR has liquidated at least 50% of its equity investment valued at such time for cash consideration. These agreements would make it costly for us to terminate certain of our senior management employees and such costs may also discourage potential acquisition proposals, which may negatively affect our stock price. See "Management—Severance Agreements."

Our products may be rendered obsolete or less attractive by changes in regulatory, legislative or industry requirements.

        Changes in regulatory, legislative or industry requirements may render certain of our products obsolete or less attractive. Our ability to anticipate changes in these requirements, especially changes in regulatory standards, will be a significant factor in our ability to remain competitive. We cannot assure you that we will be able to comply in the future with new regulatory, legislative and/or industrial standards that may be necessary for us to remain competitive or that certain of our products will not, as a result, become obsolete or less attractive to our customers.

23

The reliability of market and industry data included in this prospectus may be uncertain.

        This prospectus contains market and industry data, primarily from reports published by ACT, ATA and from internal company surveys, studies and research, related to the truck components industry and its segments, as well as the truck industry in general. This data includes estimates and forecasts regarding future growth in these industries, specifically data related to heavy- and medium-duty truck production, truck freight growth and the historical average age of active U.S. heavy-duty trucks. Such data has been published in industry publications that typically indicate that they have derived the data from sources believed to be reasonable, but do not guarantee the accuracy or completeness of the data. We have not independently verified the data or any of the assumptions on which any estimates or forecasts are based. Similarly, internal company surveys, studies and research, which while we believe to be reliable, have not been verified by any independent sources. The failure of the truck industry and/or the truck components industry to continue to grow as forecasted may have a material adverse effect on our business, results of operations or financial condition.

Other Risks Related to Our Business

Our substantial leverage and significant debt service obligations could adversely affect our financial condition or our ability to fulfill our obligations and make it more difficult for us to fund our operations.

        As of December 31, 2004, our pro forma as adjusted indebtedness was $753.8 million. Our substantial level of indebtedness could have important negative consequences to you and us, including:

•

we may have difficulty satisfying our obligations with respect to our indebtedness;



•

we may have difficulty obtaining financing in the future for working capital, capital expenditures, acquisitions or other purposes;



•

we will need to use a substantial portion of our available cash flow to pay interest and principal on our debt, which will reduce the amount of money available to finance our operations and other business activities;



•

our debt level increases our vulnerability to general economic downturns and adverse industry conditions;



•

our debt level could limit our flexibility in planning for, or reacting to, changes in our business and in our industry in general;



•

our leverage could place us at a competitive disadvantage compared to our competitors that have less debt;



•

we may not have sufficient funds available, and our debt level may restrict us from raising the funds necessary, to repurchase all of our new senior subordinated notes tendered to us upon the occurrence of a change of control, which would constitute an event of default under the new senior subordinated notes; and



•

our failure to comply with the financial and other restrictive covenants in our debt instruments which, among other things, require us to maintain specified financial ratios and limit our ability to incur debt and sell assets, could result in an event of default that, if not cured or waived, could have a material adverse effect on our business or prospects.

        You should also be aware that certain of our borrowings are and will continue to be at variable rates of interest, which exposes us to the risk of increasing interest rates. As of December 31, 2004, on a pro forma as adjusted basis, the carrying value of our total debt would have been $753.8 million, of which $478.8 million, or approximately 64%, would have been subject to variable interest rates. If interest rates increase, our debt service obligations on our variable rate indebtedness would increase

24

even though the amount borrowed remains the same. See "Selected Historical Consolidated Financial and Other Data of Accuride."

Despite our substantial leverage, we and our subsidiaries will be able to incur more indebtedness. This could further exacerbate the risks described above, including our ability to service our indebtedness.

        We and our subsidiaries may be able to incur substantial additional indebtedness in the future. Although our new senior credit facilities and the indenture governing our new senior subordinated notes contain restrictions on the incurrence of additional indebtedness, such restrictions are subject to a number of qualifications and exceptions, and under certain circumstances indebtedness incurred in compliance with such restrictions could be substantial. For example, we may incur additional debt to, among other things, finance future acquisitions, expand through internal growth, fund our working capital needs, comply with regulatory requirements, respond to competition or for general financial reasons alone. As of December 31, 2004, on a pro forma as adjusted basis, the revolving credit facility under our new senior credit facilities would have provided for additional borrowings of up to $95 million under our U.S. revolving credit facility and $5 million under our Canadian revolving credit facility. To the extent new debt is added to our and our subsidiaries' current debt levels, the risks described above would increase.

To service our indebtedness, we will require a significant amount of cash. Our ability to generate cash depends on many factors beyond our control.

        Our ability to make payments on and to refinance our indebtedness and to fund planned capital expenditures and research and development efforts will depend on our ability to generate cash in the future. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

        We cannot assure you that our business will generate sufficient cash flow from operations, that currently anticipated cost savings and operating improvements will be realized on schedule or that future borrowings will be available to us under our new credit facilities in an amount sufficient to enable us to pay our indebtedness or to fund our other liquidity needs. If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell material assets or operations, obtain additional equity capital or refinance all or a portion of our indebtedness. In the absence of such operating results and resources, we could face substantial cash flow problems and might be required to sell material assets or operations to meet our debt service and other obligations. We cannot assure you as to the timing of such asset sales or the proceeds which we could realize from such sales and we cannot assure you that we will be able to refinance any of our indebtedness, including our new senior credit facilities and new senior subordinated notes, on commercially reasonable terms or at all.

We are subject to a number of restrictive covenants which, if breached, may restrict our business and financing activities.

        Our new senior credit facilities and the indenture governing our new senior subordinated notes impose, and the terms of any future indebtedness may impose, operating and other restrictions on us. Such restrictions will affect, and in many respects limit or prohibit, among other things, our ability to:

•

incur additional debt;



•

pay dividends and make distributions;



•

issue stock of subsidiaries;



•

make certain investments;

25

•

repurchase stock;



•

create liens;



•

enter into affiliate transactions;



•

enter into sale-leaseback transactions;



•

merge or consolidate; and



•

transfer and sell assets.

        In addition, our new senior credit facilities include other more restrictive covenants and prohibit us from prepaying our other indebtedness, including our new senior subordinated notes, while borrowings under our new senior credit facilities are outstanding. Our new senior credit facilities also require us to achieve certain financial and operating results and maintain compliance with specified financial ratios. Our ability to comply with these ratios may be affected by events beyond our control.

        If we are unable to comply with the restrictions contained in the credit facilities, the lenders could:

•

declare all borrowings outstanding, together with accrued and unpaid interest, to be immediately due and payable;



•

require us to apply all of our available cash to repay the borrowings; or



•

prevent us from making debt service payments on the senior subordinated notes;

any of which would result in an event of default under our new senior subordinated notes. If we were unable to repay or otherwise refinance these borrowings when due, our lenders could sell the collateral securing our new senior credit facilities, which constitutes substantially all of our and our subsidiaries' assets. Although holders of the senior subordinated notes could accelerate the notes upon the acceleration of the obligations under our credit facilities, we cannot assure you that sufficient assets will remain after we have paid all the borrowings under our new senior credit facilities and any other senior debt to repay the senior subordinated notes.

Risks Related to the Offering and Our Common Stock

Future sales of our common stock may depress our stock price.

        The market price of our common stock could decline as a result of sales of substantial amounts of our common stock in the public market after the offering, or the perception that these sales could occur. In addition, these factors could make it more difficult for us to raise funds through future equity offerings.

        There will be 32,622,690 shares of our common stock outstanding immediately after the offering. All of the 10,000,000 shares of our common stock sold in the offering will be freely tradable without restriction or further registration under the Securities Act of 1933, as amended, except for shares purchased by our "affiliates" as defined in Rule 144 under the Securities Act. After the offering, approximately 22,622,690 shares of common stock will be either "restricted securities" or affiliate securities as defined in Rule 144. Subject to the 180-day lock-up agreements with the underwriters, these restricted securities may be sold in the future without registration under the Securities Act to the extent permitted under Rule 144. Approximately 20,873,212 outstanding shares of these restricted or affiliate securities will be eligible for sale under Rule 144 subject to applicable holding period, volume limitations, manner of sale and notice requirements set forth in applicable SEC rules, and approximately 1,749,478 shares of the restricted securities will be saleable without regard to these restrictions under Rule 144(k). See "Shares Eligible for Future Sale—Sales of Restricted Shares."

26

        We and our executive officers and directors and substantially all of our stockholders have entered into 180-day lock-up agreements with the underwriters. The lock-up agreements prohibit each of us from selling or otherwise disposing of shares of common stock except in limited circumstances. The lock-up agreements are contractual agreements, and Citigroup Global Markets Inc., Deutsche Bank Securities Inc. and UBS Securities LLC, at their discretion, can waive the restrictions of any lock-up agreement at an earlier time without prior notice or announcement and allow any of us to sell shares of common stock. If the restrictions in the lock-up agreements are waived, shares of our common stock will be available for sale into the public market, subject to applicable securities laws, which could reduce the market price for shares of our common stock. See "Shares Eligible for Future Sale—Lock-Up Agreements."

        We have also entered into an amended registration rights agreement in connection with the TTI merger providing for customary demand and piggyback registration rights to certain of our principal stockholders. Such agreement provides certain affiliates of Kohlberg Kravis Roberts & Co. L.P., or KKR, and certain affiliates of Trimaran Capital Partners, or Trimaran, with the right to cause us to register the sale of their shares of our common stock in the future. See "Certain Relationships and Related Party Transactions—Registration Rights Agreement." In addition, shares of our common stock are reserved for future issuance upon the exercise of stock options. We may also issue our common stock in connection with investments or repayment of our debt. The amount of such common stock issued could constitute a material portion of our then-outstanding common stock. We cannot predict the size of future issuances of our common stock or the effect, if any, that future sales and issuances of shares of our common stock would have on the market price of our common stock.

You will experience immediate and substantial dilution as a result of the offering.

        You will pay a price per share that substantially exceeds the per share value of our tangible assets after subtracting our total liabilities. As of December 31, 2004, after giving effect to the 591-for-one split of our common stock, our pro forma net tangible book value was a deficit of $32.33 per share of common stock. After giving effect to the issuance and sale of 10,000,000 shares of our common stock in the offering, less underwriting discounts, offering-related expenses and other expenses and the completion of the transactions outlined in "Pro Forma Consolidated Financial Data," including the application of the net proceeds in accordance with "Use of Proceeds," our pro forma as adjusted net tangible book value as of December 31, 2004 would have been a deficit of $11.75 per share of common stock. This represents an immediate increase in net tangible book value of $20.58 per share to existing stockholders and an immediate dilution of $22.75 per share to new investors purchasing shares of our common stock in the offering. See "Dilution."

Possible volatility in our stock price could negatively affect us and our stockholders.

        The trading price of our common stock may be volatile in response to a number of factors, many of which are beyond our control, including actual or anticipated variations in quarterly financial results, changes in financial estimates by securities analysts and announcements by our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments. In addition, our financial results may be below the expectations of securities analysts and investors. If this were to occur, the market price of our common stock could decrease, perhaps significantly.

        In addition, the U.S. securities markets have experienced significant price and volume fluctuations. These fluctuations often have been unrelated to the operating performance of companies in these markets. Broad market and industry factors may negatively affect the price of our common stock, regardless of our operating performance. In the past, following periods of volatility in the market price of an individual company's securities, securities class action litigation often has been instituted against that company. The institution of similar litigation against us could result in substantial costs and a

27

diversion of our management's attention and resources, which could negatively affect our business, results of operations or financial condition.

Our common stock may not trade actively, which may cause our common stock to trade at a discount and make it difficult for you to sell your stock.

        This is our initial public offering, which means that our common stock currently does not trade in any market. Upon the consummation of the offering, our common stock may not trade actively. In addition, our common stock may have limited trading volume, and many investors may not be interested in owning our common stock because of the inability to acquire or sell a substantial block of our common stock at one time. This illiquidity could have an adverse effect on the market price of our common stock. An illiquid market for our common stock may result in price volatility and poor execution of buy and sell orders for investors. The initial public offering price for shares of our common stock is or will be determined by negotiations between us and the underwriters and may bear no relationship to the price at which the common stock will trade after the offering.

Our ability to pay dividends on our common stock will be limited.

        Under Delaware law, we may pay dividends, in cash or otherwise, only if we have surplus in an amount at least equal to the amount of the relevant dividend payment. Any payment of cash dividends will depend upon our financial condition, capital requirements, earnings and other factors deemed relevant by our board of directors. Further, our new senior credit facilities and the indenture governing our new senior subordinated notes will restrict our ability to pay cash dividends. Agreements governing future indebtedness will likely contain similar restrictions on our ability to pay cash dividends. We do not intend to pay dividends on our common stock for the foreseeable future. See "Dividend Policy."

Our principal stockholders, executive officers and directors own a large percentage of our common stock and will be able to control substantially all corporate decisions.

        Immediately after the offering, our principal stockholders will beneficially own, in the aggregate, approximately 64.5% of our outstanding common stock, including 39.1% and 17.6% of our outstanding common stock beneficially owned by KKR and entities affiliated with Trimaran Investments II, L.L.C., respectively, and our executive officers and directors will beneficially own, in the aggregate, approximately 61.2% of our outstanding common stock. Our principal stockholders, executive officers and directors will together beneficially own approximately 69.1% of our outstanding common stock (taking into account that some shares are considered beneficially owned by both principal stockholders and executive officers). In addition, immediately after the offering, KKR and entities affiliated with Trimaran Investments II, L.L.C. each have the right to appoint four and three members of our board of directors, respectively. As a result, our principal stockholders, executive officers and directors, as a group, will be able to influence or control substantially all matters requiring approval by our stockholders, including, without limitation, the election of directors and mergers, consolidations and sales of all or substantially all of our assets, and they may do so in a manner with which you may not agree or which may be adverse to your interests. For example, they could (1) cause our company to enter into transactions with their affiliates that are adverse to our interests or (2) cause us to redeem or make payments on securities owned by them. In addition, this concentration of ownership may have the effect of preventing, discouraging or deferring a change of control, which could depress the market price of our common stock. See "Principal Stockholders and Selling Stockholders," "Certain Relationships and Related Party Transactions" and "Description of Capital Stock—Common Stock."

28

Provisions of our charter documents and the General Corporation Law of Delaware may inhibit a takeover, which could negatively affect our stock price.

        Provisions of our charter documents and the General Corporation Law of Delaware, the state in which we are organized, could discourage potential acquisition proposals or make it more difficult for a third party to acquire control of our company, even if doing so might be beneficial to our stockholders. Our certificate of incorporation and bylaws provide for various procedural and other requirements that could make it more difficult for stockholders to effect certain corporate actions. For example, our certificate of incorporation authorizes our board of directors to determine the rights, preferences, privileges and restrictions of unissued series of preferred stock without any vote or action by our stockholders. Our board of directors can therefore authorize and issue shares of preferred stock with voting or conversion rights that could adversely affect the voting or other rights of holders of our common stock. Additional provisions that could make it more difficult for stockholders to effect certain corporate actions include:

•

the sole power of a majority of the board of directors to fix the number of directors and to fill any vacancy on the board of directors;



•

limitations on the removal of directors; and



•

the inability of stockholders to act by written consent or to call special meetings.

        See "Description of Capital Stock." These provisions may make it more difficult or expensive for a third party to acquire a majority of our outstanding voting stock or may delay, prevent or deter a merger, acquisition, tender offer or proxy contest, which may negatively affect our stock price.

We will incur increased costs as a result of being a public company.

        Although Accuride has had publicly traded debt securities outstanding for approximately six years and has been a voluntary reporting company during that time, as a company with publicly traded equity securities, we expect to incur additional legal, accounting and other expenses that we did not incur as a private company. In addition, the Sarbanes-Oxley Act of 2002, as well as related rules subsequently implemented by the SEC and the New York Stock Exchange, have required changes in corporate governance practices of public companies. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly. For example, as a result of this offering, we will create additional board committees and will adopt additional policies regarding internal controls, disclosure controls and procedures. In addition, we will incur additional costs associated with our public company reporting requirements. We also expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified persons to serve on our board of directors or as executive officers. Despite the fact that TTI had publicly traded equity securities until it was acquired in a going-private transaction in March 2000 and despite Accuride's experience as a voluntary reporting company, we cannot predict or estimate the amount of additional costs we will incur or the timing of such costs.
