What Dorman Products makes

Dorman Products designs, engineers, packages, and distributes replacement and upgrade parts for the motor vehicle aftermarket, covering passenger cars, light-, medium-, and heavy-duty trucks, and specialty vehicles. The company's catalog runs to more than 118,000 distinct parts by its own count on its corporate site, and it describes the range as spanning chassis to body, underhood to undercarriage, and hardware to complex electronics. Dorman's founding idea, dating to 1918, was to release aftermarket alternatives to parts that owners could once only buy from the original vehicle manufacturer, and it still frames its work as identifying frequently failing parts and engineering repair solutions for them.

The business runs through three reporting segments. Light Duty is the core Dorman and OE Solutions passenger-vehicle business, and it accounts for the large majority of sales, roughly $1.69 billion of the company's $2.13 billion in fiscal 2025 net sales. Heavy Duty operates under the Dayton Parts brand, serving the commercial-truck aftermarket. Specialty Vehicle is the SuperATV brand, which makes parts and accessories for utility and side-by-side off-road vehicles. Product categories across the group include steering and suspension, brakes and undercar, underhood, body components, fasteners and hardware, service-line products, and electronics such as modules and sensors. Dorman is a member of MEMA Aftermarket Suppliers, the trade group for aftermarket component manufacturers, and CEO Kevin Olsen serves as its First Vice Chair.

Financial performance

Dorman reported record full-year 2025 net sales of $2,130.3 million, up 6.0 percent from $2,009.2 million in 2024, according to the company's fourth-quarter and full-year 2025 results. Gross margin reached 42.1 percent in 2025, up from 40.1 percent, and diluted earnings per share rose 8 percent to $6.64, with adjusted diluted EPS up 24 percent to $8.87. Income from operations was about $299.5 million in 2025, a roughly 14.1 percent operating margin. The 2024 fiscal year set the prior record at $2.0 billion in net sales, $292.9 million of operating income, and $190.0 million of net income, per the company's 2024 annual report.

Momentum has continued into fiscal 2026. Second-quarter net sales were $544.6 million, up 0.7 percent, with diluted EPS of $2.93, up 53 percent, and $152.6 million of operating cash flow in the quarter. Those second-quarter earnings benefited from the recovery of IEEPA tariff costs recognized in prior periods, which the company said added about $1.18 to adjusted diluted EPS. Dorman guided full-year 2026 to net sales growth of 3 to 5 percent and adjusted diluted EPS of $8.50 to $8.80. The company grew through acquisitions as well as organically, buying Dayton Parts for $338 million in 2021 and SuperATV for roughly $590 million in 2022.

Ownership and history

Dorman Products was founded in 1918 and is headquartered at 3400 East Walnut Street in Colmar, Pennsylvania, north of Philadelphia. It began as a family-led automotive hardware business and grew into one of North America's larger aftermarket parts suppliers. The company trades on the Nasdaq under the ticker DORM and carried a market capitalization of about $3.6 billion in mid-2026. Kevin M. Olsen is Chairman, President, and Chief Executive Officer; he joined Dorman as chief financial officer in 2016, became CEO in 2019, and added the chairman role in April 2026, when longtime chairman Steven Berman moved to a director seat.

The company employs more than 3,800 people across 29 locations, with design and engineering teams at its Pennsylvania headquarters and product engineers positioned in manufacturing facilities in the United States, China, India, and Taiwan. In January 2026 Dorman announced a slate of senior leadership changes: Charles W. Rayfield joined as senior vice president and chief financial officer, Nathan J. Porter as senior vice president and chief operations officer, Eric B. Luftig was promoted to President, Light Duty, and Steven A. Bashir joined as President, Heavy Duty. Its family of brands includes Dorman and OE Solutions, Dayton Parts, SuperATV, and Ingalls Engineering.

Certifications and quality

Dorman states that it produces to ISO 9001 and IATF 16949 manufacturing standards, the latter being the automotive-sector quality management standard, and that it applies the Advanced Product Quality Planning (APQP) framework across its five-phase product development process. The company describes an engineering approach built on rapid prototyping, finite element analysis, and in-house product engineers embedded in its global manufacturing network. These are the company's own published claims; certificate numbers and issue dates are not posted on the corporate site. Dorman positions many of its parts as designed to meet or exceed the specifications of the original equipment they replace, a common posture among engineering-led aftermarket suppliers.

Known customers

Dorman sells primarily in the United States and does not publish an individual customer list. Its own filings describe the channels it serves rather than named accounts:

Because Dorman is itself a supplier to the repair aftermarket rather than a direct OEM production supplier, its customer base is the distribution and retail network that reaches professional installers and vehicle owners, not a roster of automakers.

Sourcing evidence

Dorman's US import record is consistent with a company that has parts manufactured to its specifications by a global network and imports them for domestic distribution. Its importer-of-record profile shows 2,149 ocean bill-of-lading shipments on record, with the most recent dated September 21, 2026, indicating active, current sourcing. Named foreign suppliers on those records include Hicom Diecastings, King Shing Automobile Parts, and Xiamen Kingtom Rubber and Plastic, alongside logistics intermediaries such as Damco. A related entity at the same Colmar address, RB Distribution, carries a further 634 shipments on record. This overseas manufacturing footprint is also why tariff policy matters to Dorman's results, as the IEEPA tariff cost recovery in its 2026 earnings shows, and it is relevant to buyers weighing nearshoring and tariff exposure.

Coverage caveats apply: these are US ocean-freight records only, so air, truck, and rail movements do not appear; some records name freight intermediaries rather than the actual manufacturer; and product categories come from declared manifest codes, which are noisy. Absence of a record is not evidence of absence.
