Fox Performance Series 2.0 Rear Smooth Body Reservoir Shock for 1.5-3" Lift; Select 2020-2026 GM 2500/3500 HD

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

The Fox Performance Series 2.0 Rear Smooth Body Reservoir shocks are engineered to transform your heavy-duty truck's suspension performance. Designed to accommodate 1.5 to 3 inches of rear lift, these shocks deliver a connected, predictable ride that reduces vehicle sway and improves off-road articulation by extending drop-out travel. The external reservoir system increases oil capacity to dissipate heat faster than traditional internal designs, preventing performance fade during heavy towing or aggressive off-road use.

Constructed with a clear-anodized 6061-T6 aluminum body, these shocks dissipate heat four times more effectively than conventional steel shocks. The internal floating piston (IFP) mono-tube design separates the high-pressure nitrogen gas from the shock oil, ensuring consistent damping regardless of terrain. Each unit is fully serviceable and features black-anodized CNC-machined components for long-term corrosion resistance in harsh environments.
