Fox Performance Elite Series 2.5 Rear Adjustable Reservoir Shocks for 2020-2026 GM 2500/3500 HD (0-1" Lift)

Fits 2020-2026 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD.

Enhance your heavy-duty truck's handling and heat management with Fox Performance Elite Series 2.5 rear adjustable shocks. Specifically engineered for the 2020-2026 GM 2500/3500 HD platform, these shocks utilize a large-diameter 2.5-inch aluminum body to dissipate heat significantly faster than traditional steel alternatives. This design increases internal oil volume and employs race-developed high-flow pistons to maintain consistent damping control during heavy towing or aggressive off-road use.

Equipped with external reservoirs, these shocks offer the widest range of adjustability Fox provides, allowing you to fine-tune the suspension for specific loads and terrain. The 7/8-inch hard chromed shock shaft and redundant seal pack are built for harsh environments, ensuring long-term reliability. These units are fully serviceable and designed for a lifetime of use on vehicles with 0 to 1 inch of rear lift.
