Fox 20+ GM 2500/3500 HD 2.0 Performance Series IFP Rear Shock 1.5-3in Lift

If you're looking to get more out of your 2020-2025 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra counterpart, this FOX 2.0 Performance Series IFP rear shock is a solid option. It's built with application-specific valving, meaning it's tuned from the factory to work best with your truck's suspension setup. This helps provide a more comfortable ride on the street while also giving you better control when you head off-road.

The shock body is made from aluminum, which helps dissipate heat more effectively than steel, especially important during extended use. Inside, an Internal Floating Piston (IFP) design keeps the oil and high-pressure nitrogen gas separated, which helps maintain consistent damping performance. The components are CNC machined and black anodized for durability, and the shock uses Teflon-lined, heat-treated spherical bearings for smooth operation. Because it's a FOX Performance Series shock, it's also designed to be serviceable and tunable, meaning you can rebuild or re-valve it down the road to keep it performing its best for a long time.

This shock is designed to work with trucks that have a 1.5 to 3-inch suspension lift.
