Interior & Cabin Components · 5 of the top 100
Drivers live in these trucks. Cabin filters, switches and interior hardware sell because comfort and visibility are daily-use items, not luxuries.

Engine & Performance · 19 of the top 100
Filters, water pumps and the service items every PM interval consumes. These are the quiet volume kings — bought four and ten at a time by shops that maintain fleets on a calendar, not on a breakdown.

Air & Brake Lines · 5 of the top 100
Gladhands, coils and fittings: pennies each, truck-stopping when they fail. Every trailer swap works them, so they're consumables in all but name.

Fuel System · 4 of the top 100

Suspension & Steering · 8 of the top 100
Shocks, torque rods and bushings — the parts the Pacific Northwest's freeze-thaw potholes eat first. Worn suspension also chews tires, which is why fleets replace early.

Trailers: Body & Frame · 1 of the top 100
Trailer body hardware — panels, doors and frame parts that take the same dock abuse the tractor's body does.
Body & Exterior · 28 of the top 100
No surprise this is the biggest group: body parts don't wear out on a schedule — they get hit. Deer strikes, dock bumps, yard clips. When it happens the truck is visibly damaged, DOT notices, and the fix can't wait, so bumpers, mirrors, fairings and grilles move constantly.
