Dorman Products is a leading supplier of replacement and upgrade parts for the motor vehicle aftermarket, offering tens of thousands of parts across light-duty, heavy-duty, and specialty vehicle categories. The company designs, engineers, and sources a broad range of products covering engine, undercar, steering and suspension, body, electronics, and hardware—many historically available only from original equipment manufacturers or salvage yards—and markets them primarily under its own brands to consumers, repair shops, dealerships, distributors, and online retailers across North America and international markets. Revenue derives principally from nondiscretionary repair parts, which are less cyclical than discretionary spending; the company manufactures certain heavy-duty and specialty vehicle products and sources the remainder from a diversified global supplier base, distributing through company and third-party logistics infrastructure.
