Product Details

Fox shocks for the 2024-2026 GMC Sierra 2500 HD: this FOX Performance Elite Series 2.5 rear shock absorber set is one of the Sierra 2500 HD shocks Fox builds for this vehicle for 0 to 1 inches of lift.

Fox Sierra 2500 HD shocks in the Performance Elite Series 2.5 line use a 2.5 inch aluminum body with a piggyback reservoir that adds oil volume and keeps it apart from the nitrogen gas charge. Fox fits a DSC - Dual Speed Compression adjuster to this part, so damping can be changed without taking it off the vehicle. 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 883-26-085. Fox's fitment note for this vehicle: Excludes AT4X Model.
