Fox 99+ Chevy HD 2.0 Performance Series 11.1in. Smooth Body IFP Rear Shock (Aluminum) / 4-6in. Lift

What you get here is a single FOX 2.0 Performance Series rear shock absorber, designed for a range of 1999 and newer Chevrolet and GMC heavy-duty trucks and SUVs. This shock is built to handle a 4-6 inch lift and is specifically valved to maximize performance for these vehicles. It uses an Internal Floating Piston (IFP) design to separate the oil from the high-pressure nitrogen gas, which helps prevent oil aeration and ensures consistent damping control.

The aluminum body is a key feature here; it dissipates heat much faster than a steel body, which is crucial for maintaining performance during extended use, especially off-road or under heavy loads. The components are CNC machined from aluminum and black anodized for durability and a clean look. Inside, you'll find Teflon-lined, heat-treated spherical bearings that allow for smooth movement and long-lasting performance. This shock is also 100% serviceable and tunable, meaning you can rebuild or re-valve it down the road to keep it performing at its best.

This shock is a solid option for improving both your on-road ride comfort and your off-road handling. It's designed to fit a wide variety of popular trucks like the Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD, among others. Because it's designed for a specific lift height range, it helps ensure proper suspension geometry and travel for your lifted vehicle.
