Fox 2011+ GMC Sierra 2500/3500 HD 0-1in Lift Rear 2.5 Performance Series Smooth Body IFP HTO Shock

If you're looking to get more out of your 2011-2025 Chevrolet Silverado 2500 HD's suspension, this rear shock from Fox is a solid option. It's built to handle both comfortable daily driving and tougher off-road conditions, offering a noticeable improvement in how your truck rides and handles.

This shock features a 2.5-inch diameter body made from impact-extruded 6061-T6 aluminum, which is strong and resists corrosion thanks to its Type II clear-anodized plating. Inside, it uses a high-flow, velocity-sensitive damping system that adjusts automatically to the terrain, providing a smooth ride on pavement and controlled handling when you go off-road. The internal floating piston (IFP) separates the oil and gas, and the hydraulic top-out (HTO) piston helps prevent harsh bottoming out. The 5/8-inch hard chrome shaft is built to last. Fox tunes these shocks specifically for your truck, ensuring they work well right out of the box.

This shock is designed for trucks with a 0 to 1-inch lift in the rear and is fully rebuildable and re-tunable, meaning you can service it to keep it performing at its best for a long time.
