Truck Differential & Axle Parts

Keep your drive axles turning with heavy-duty truck differential and axle parts built for Class 8 and medium-duty work. This category covers the components that move power from the driveline to the wheels: ring and pinion sets, differential carriers and cases, spider and side gears, axle shafts, plus the bearings, seals, and hardware that hold it all together.

Not sure which ratio, spline count, or carrier series you're running? Our team cross-references OEM, competitor, and superseded part numbers so you order the right piece the first time. Most stock orders ship same-day, with free freight over $1,000.

Choosing the Right Truck Differential & Axle 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.

Can't Find the Right Part?

Text us the part number or a photo of the tag — we'll cross-reference it and quote you the right one.
