Description

FOX 2.0 Performance Series Rear Shock – 2020–2026 Silverado/Sierra 2500HD/3500HD (1.5″–3″ Lift)

Upgrade your ride quality and control with the FOX 2.0 Performance Series Rear Shock, engineered to transform the performance of your Silverado or Sierra HD both on and off-road. These shocks utilize race-proven damping control to deliver a smooth, comfortable on-road ride while maintaining predictable handling in demanding conditions. The precision aluminum body increases cooling capacity and resists corrosion, while the internal floating piston (IFP) mono-tube design separates shock oil from the high-pressure nitrogen gas chamber to eliminate aeration and maintain consistent performance. Combined with application-specific valving and a high-flow damping piston, this shock provides reliable, controlled ride quality capable of handling even the roughest terrain.
