Heavy-Duty Truck Suspension Parts

Keep your rig planted and tracking straight with heavy-duty truck suspension parts built for Class 8 and severe-duty service. JAK'S Diesel stocks the wear items that take the pounding mile after mile: shocks, leaf and air spring components, bushings, U-bolts, torque rods, and shackle hardware.

Worn suspension shows up as bottoming out, harsh ride, drifting, uneven tire wear, and cab shake. If you're not sure exactly what you need, send us the OEM, competitor, or superseded part number and we'll cross-reference it. In-stock parts ship same-day from Colorado, free freight over $1,000.

Choosing the Right Heavy-Duty Truck Suspension 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.
