GMC Sierra 2500 HD/Sierra 3500 HD & Chevrolet Silverado 2500 HD/Silverado 3500 HD, FOX Performance 2.5 Smooth Body IFP HTO Shock, Rear, 1.5-2.5in Lift

Washboard roads and long gravel miles find the limits of worn factory shocks fast, and the Sierra 2500 HD starts to bounce and wander. It turns a good trip into a long, tiring one.

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.
