Choosing the Right Truck Driveline Parts

Heavy-duty diesel components must be matched to the exact engine and application. Before ordering from this collection, verify the part number, engine model, engine serial number, and any casting or calibration number shown on the original component.

Fitment information to have ready

  • OEM, dealer, casting, or interchange part number
  • Engine manufacturer, model, and engine serial number (ESN)
  • Truck year and model when the component is chassis-specific
  • Core details for remanufactured or exchange components

Need a fitment check?

Use the OEM cross-reference tool or text a clear photo of the part tag to (720) 445-6249. A JAK'S Diesel specialist can confirm the match before the part ships.
