Class 8 parts catalog

How to shop this catalog

This page lists all forty Class 8 parts we publish with prices in U.S. dollars. Use the make and department filters above the grid to shrink the list, then open a product page for the full fitment table, interchange numbers, and PayPal checkout for the part price. The home page shows only a short featured set; everything else lives here or in a department page.

Filters is the largest department with eight oil, fuel, and fuel/water listings, including the Donaldson P551000 separator for Cummins highway applications. Brakes and air holds seven items covering dryer cartridges, chambers, shoes, seals, slack adjusters, and glad hands. Clutch and drivetrain, cooling, suspension, lighting, and cab each carry four parts. Lubricants adds five oil, SCA coolant concentrate, and DEF options for service lanes that buy fluids with the filters.

Fitment rows name Freightliner, Peterbilt, Kenworth, Volvo, and Mack models where we have confirmed applications. A missing make on a card does not always mean the part will not fit; it means we have not published a row. Email the VIN and the old part stamp to support@aonetruckauto.com when you need a hand check.

Shipping is quoted before a carrier is booked. PayPal on each product page collects the listed part total for the quantity you choose. Freight and sales tax, when they apply, are confirmed by email. Heavy clutch and some brake kits may ship freight instead of parcel; the product page states the usual method.

If you already know the repair, jump to a department: Brakes & Air, Filters, Clutch & Drivetrain, Engine Cooling, Suspension, Lighting, Cab & Exterior, or Lubricants. For measurement and PM planning, see the technical guides.
