Product Details

Fox shocks for the 2019-2021 GMC Sierra 1500: this FOX 2.5 Performance Series rear shock absorber is one of the Sierra 1500 shocks Fox builds for this vehicle for 2.5 to 4 inches of lift.

Fox Sierra 1500 shocks in the 2.5 Performance Series line use a 2.5 inch aluminum body with an internal floating piston, which keeps the shock oil apart from the nitrogen gas charge. The aluminum body sheds heat faster than steel, which helps the damping stay consistent on long, rough runs. Fox sets the valving for the vehicle it is listed for.

This listing is Fox suspension part number 987-24-028. Fox's fitment note for this vehicle: AT4 Fits 0-2 in. Lift Only. Fox states for the install: 2 in. Bump stop spacer required for non-AT4 models.
