Fox 99+ Chevy HD 2.0 Performance Series 13.1in. Smooth Body IFP Rear Shock (Aluminum) / 7-10in. Lift

If you're looking to get more out of your lifted 1999-2019 Chevrolet or GMC heavy-duty truck, or even your Hummer H2, this FOX 2.0 Performance Series rear shock is a solid option. It's built to handle the demands of a 7 to 10-inch lift, offering a noticeable improvement in both how your vehicle feels on the road and how it performs when you take it off-road. The race-proven damping technology helps keep things comfortable during daily driving while providing predictable control when you hit rougher terrain.

This shock features an aluminum body, which is great because it dissipates heat faster than steel, helping to maintain consistent performance even under heavy use. Inside, an IFP (Internal Floating Piston) design keeps the oil and high-pressure nitrogen gas separated, preventing aeration and ensuring a smooth, responsive feel. The components are CNC machined from aluminum and black anodized, and the shock uses Teflon-lined, heat-treated spherical bearings for smooth movement and long life. Plus, it's designed to be 100% serviceable and tunable, meaning you can keep it performing at its best for a long time.

This shock is application-tuned, meaning FOX has developed specific valving for vehicles like the Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD, ensuring it works well with their suspension characteristics. It's a well-built component designed to handle the extra stress that comes with a significant lift kit.
