Fox 11-19 GMC Sierra 2500/3500 HD 0-1in Lift Front 2.5 Performance Series Smooth Body IFP HTO Shock

Fox is known for making high-performance suspension components, often seen on race vehicles. This 2.5 Performance Series shock is built to give your 2011-2019 Chevrolet Silverado 2500 HD a noticeable upgrade in how it handles both on the pavement and when you venture off-road. It's designed to work with a 0 to 1-inch lift, making it a straightforward addition for many truck owners.

The shock body itself is made from impact-extruded 6061-T6 aluminum, which is then clear-anodized for corrosion resistance. Inside, you'll find a high-flow, velocity-sensitive damping system that adjusts to road conditions, along with an internal floating piston (IFP) and a Hydraulic Top Out (HTO) piston. These features work together to provide a comfortable ride on the street and predictable control when you're tackling rougher terrain. The 5/8-inch hard chrome shaft adds to its durability and smooth operation.

This shock absorber is application-specific, meaning the valving is tuned for your Silverado 2500 HD to maximize its performance. It's also fully rebuildable and re-tunable, so you can maintain its performance over the long haul.
