Dorman Bundle
How did Dorman transform aftermarket parts into engineering improvements?
A century of targeted engineering turned a regional parts seller into a design-led aftermarket innovator, focused on 'OE FIX' replacements that improve reliability and value. Dorman scaled by solving common failure points for pros and DIYers while the U.S. fleet aged past 12.6 years in 2024.
Dorman began in 1918 as R&B, Inc. in Philadelphia, rebranded later, and now offers over 118,000 SKUs from Colmar, PA, with ~$2.0–$2.1 billion annual sales in 2023–2024 through major channels. Read a product-market perspective: Dorman Porter's Five Forces Analysis
What is Brief History of Dorman Company? Founded to fix chronic parts failures, it evolved into a data-driven supplier turning repair challenges into repeatable, scalable product innovations.
What is the Dorman Founding Story?
Dorman’s founding story begins in 1918 in Philadelphia, when R&B, Inc. served independent garages and jobbers with hard-to-find automotive and hardware parts during rapid U.S. motorization; the business prioritized quick fulfillment and practical fixes that outperformed original equipment (OE) parts.
Founding Story
R&B, Inc. started as a small distributor in 1918, evolving into the Dorman brand by packaging engineered improvements for repeat failure points and building trust with professional installers.
- Founded in 1918 in Philadelphia as R&B, Inc.; focused on supplying hard-to-find parts to independent garages and local jobbers.
- Initial model: distribution of small parts and fasteners from a modest warehouse with rapid fulfillment and tight working-capital management.
- Early product evolution included light re-engineering to correct repeat failure points; the trade name 'Dorman' distinguished engineered fixes from commodity replacements.
- Bootstrapped funding via retained earnings and extended supplier terms; disciplined capital management enabled survival through the Great Depression and WWII rationing.
Practical, customer-driven innovation—prioritizing mechanic feedback over patent-heavy R&D—formed the cultural core that later formalized into programs like OE FIX and underpinned Dorman Company history and Dorman Products timeline entries; by mid-20th century this approach drove measurable growth in market share for aftermarket parts.

What Drove the Early Growth of Dorman?
Dorman Products grew from a regional supplier into a national aftermarket innovator by building catalog depth, expanding distribution in the Northeast, and layering application engineering and sourcing to serve professional and DIY channels.
1930s–1960s: Regional density
Started as R&B, the firm built cataloged assortments of clips, fasteners and small parts to supply jobbers across the Northeast; printed catalogs and larger Philadelphia-area facilities enabled next-day availability as Detroit’s Big Three standardized platforms.
1970s–1980s: Professionalization
As the aftermarket professionalized, private‑label and branded offerings won national retail and warehouse-distributor shelf space; sourcing and quality-control investments supported entry into higher-complexity categories like window regulators and intake components.
1990s: Scale and public listing
SKU proliferation and national accounts drove scale; listing on NASDAQ provided working-capital to expand distribution centers for two-day U.S. service. The company’s engineering-led 'problem-solver' approach began differentiating it from pure distributors.
2000s: Application engineering and data
Formalized application-specific engineering launched thousands of SKUs annually and created fitment and failure-mode databases; expansion into heavy- and medium-duty truck segments broadened the total addressable market and early digital fitment tools improved installer conversion.
Dorman Company history shows category expansion through the 2010s into powertrain, chassis and electronics, with near-shore and global sourcing and deepened channel partnerships with AutoZone, Advance, O’Reilly and NAPA as the U.S. aftermarket surpassed $400 billion by the early 2020s.
2021–2022: Transformative acquisitions
Acquisitions of Dayton Parts (heavy-duty undercarriage/suspension; reportedly mid‑$300 million) and SuperATV (powersports; enterprise value ~$490 million) added commercial-vehicle breadth and powersports reach, supporting 2022 net sales above $1.7 billion and positioning 2023 around $2.0 billion.
2023–2024: Optimization and resilience
With channel inventory normalization and inflationary pressures, the company emphasized pricing discipline, SKU rationalization, working-capital optimization and supply-chain normalization while continuing to release thousands of SKUs to defend its moat in long‑tail, failure‑prone parts.
