GMC Sierra 3500 HD/Sierra 2500 HD & Chevrolet Silverado 2500 HD/Silverado 3500 HD, FOX Performance 2.5 Smooth Body IFP HTO Shock, Rear, 6.5in Lift

Washboard roads and long gravel miles find the limits of worn factory shocks fast, and the Sierra 3500 HD starts to bounce and wander. The worry is always whether the rig and the load will make it back without trouble.

The FOX Performance 2.5 Smooth Body IFP HTO Shock is built to fix that. An internal floating piston keeps the oil apart from the high-pressure nitrogen charge. It can be serviced and rebuilt, so it keeps working long after the first season. A hard chrome plated shaft stands up to grit and rock strikes. Fit it, torque it to spec, and get back to the trip. What follows is a smoother, more controlled ride and the confidence to keep exploring.
