GMC Sierra 3500 HD/Sierra 2500 HD & Chevrolet Silverado 2500 HD/Silverado 3500 HD, FOX Performance 2.5 Smooth Body IFP HTO Shock, Rear, 4-6in Lift

A tired factory shock lets the Sierra 3500 HD wallow on washboard and float over whoops, and every rut turns into a jolt through the cab. That wears on a driver and makes every trip less fun than it should be.

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. Bolt it in, set it up for the load, and hit the trail. The payoff is a planted rig, less fatigue behind the wheel, and more time enjoying the trail.
