Engine & Drivetrain Overview

Your truck's engine and drivetrain make power and put it to the ground, so a blown gasket, worn clutch, or failing U-joint costs uptime and can strand the truck. Van Horn Truck Parts carries engine and drivetrain parts cross-referenced to Cummins, Detroit, PACCAR, Mack, Eaton, Spicer/Dana, and Automann part numbers.

Browse by sub-category — engine gaskets and seals, clutches and clutch brakes, U-joints and yokes, motor mounts, oil-system parts, and transmission and differential components. Match each part by your engine or transmission make and model or the number on the old component.

Mechanic & Fitment Specs:

  • Sub-categories: Engine gaskets/seals, clutches, U-joints/yokes, motor mounts, oil system, transmission, differential
  • Match by: Engine/transmission make/model, old part number
  • Cross-references: Cummins, Detroit, PACCAR, Mack, Eaton, Spicer/Dana, Automann
  • Buying tip: Confirm your engine or transmission model before matching drivetrain parts
