Make Parts for Cars the Factory Stopped Supporting
the problem
When vehicles aged past dealer support, owners faced junkyards or dealer-only parts priced as monopolies.
background
Dorman, branding itself NEW SINCE 1918, sells approximately 133,000 different automotive replacement parts, fasteners and service-line products — a catalog whose breadth is the strategy.
The company specializes in parts for vehicles the original manufacturers no longer supply well, including dealer-exclusive items re-engineered for the independent aftermarket, where no other new part exists.
what everyone would do
Compete on the high-volume commodity parts that everyone stocks.
what they saw
The aftermarket's value hides in parts nobody bothers to make. Each is a tiny monopoly — the dealer prices it as one, and independent tooling captures that margin a hundred thousand times over.
the move
Mine the aftermarket's forgotten tail: when a part dies on an aging fleet, the dealer holds a monopoly and the junkyard holds a gamble. Dorman reverse-engineers the part, tools it new, and lists it in a catalog of over a hundred thousand SKUs — each low-volume, each defensible, each sold exactly when the alternative is a dead car.
why it works
Aging fleets guarantee demand; dealer-only supply leaves price umbrellas; each solved part compounds catalog depth that distributors shelf-space by shelf-space; and low volumes deter imitators part by part.
the payoff
A 133,000-SKU catalog of replacement parts built into a public company serving the independent aftermarket (SEC 10-K).
where it breaks
It fails when tooling costs exceed a part's lifetime volume, when vehicle scrappage accelerates past catalog amortization, and when OEMs extend parts support into the tail themselves — the tail must stay abandoned for the model to pay.
what came after
The archetype of long-tail parts supply: as vehicle fleets age and electronics proliferate, the forgotten-part backlog keeps growing.
