The FOX 2.0 Performance Series Shocks with Reservoir are high-performance, aluminum-bodied shock absorbers designed for 2011-2019 GMC Sierra 2500 HD models with 1.5 to 3.5-inch lift. These shocks feature a smooth body design with a clear anodized aluminum finish that dissipates heat efficiently, ensuring consistent performance under demanding conditions. The external reservoir increases oil and nitrogen capacity, enhancing damping control and ride quality. CNC-machined from 6061-T6 aluminum, the shocks include a black anodized reservoir clamp and high-flow damping piston, providing race-level handling and durability for off-road and heavy-duty applications.
Designed for 2011-2019 GMC Sierra 2500 HD trucks with 4WD or RWD configurations, these shocks are a direct bolt-on upgrade that reuses factory hardware for installation. They are suitable for vehicles with or without lift kits that do not alter OE mounts, and they come with a one-year warranty against defects. The kit includes four shocks—two front and two rear—along with reservoir clamps, washers, bushings, and nuts. These shocks are ideal for off-road, towing, and heavy-duty use, delivering predictable handling and improved ride comfort on rough terrains.
