Performance Series 2.0 Reservoir Rear Shock

The Fox Performance Series 2.0 Reservoir shock is engineered to deliver race-winning performance in a hassle-free, bolt-on package for lifted trucks. Constructed with a heat-reducing, clear-anodized aluminum shock body, it dissipates heat more effectively than traditional steel bodies, ensuring consistent performance under demanding conditions. This rear shock features a 14.12-inch travel and is designed for 7-10 inches of rear lift. Its 2.0-inch impact-extruded 6061-T6 aluminum body resists rust over time, while the 5/8-inch hard chrome-plated, heat-treated alloy steel shaft provides durability. The external reservoir increases oil and nitrogen capacity, contributing to a striking race-inspired aesthetic and enhanced cooling. All black anodized components, including the reservoir mounting clamp, are CNC-machined from 6061-T6 billet aluminum. The shock absorber utilizes a race-developed high-flow piston and application-specific valving to provide a predictable and smooth ride, capable of handling the roughest terrain. Redundant sealing systems, including a main seal, wiper seal, and scraper seal, ensure long-term reliability. The shock has an extended length of 34.02 inches and a compressed length of 19.9 inches, with ES6 top and bottom mounts. This vehicle-specific shock absorber is designed for 2001-2010 Chevrolet Silverado 2500 HD, Silverado 3500 HD, GMC Sierra 2500 HD, and Sierra 3500 HD models.
