Overview
Give your Chevy Silverado or GMC Sierra 2500HD truck a race-winning technology upgrade to improve damping in any terrain with FOX Performance Elite Series 2.5 rear shocks with Dual Speed Compression (DSC) Reservoir Adjusters. Designed to fit a 6.5-inch suspension lift kit. Before any FOX shocks reach production, they've had to stand the test of time and live up to incredible abuse by the fastest athletes in racing. FOX pushes the boundaries to give you that same precise control and race-proven performance you can feel in a bolt-on solution.
Coil-over shocks provide suspension damping and suspend the weight of the vehicle. The integrated coil spring can be adjusted for preload and ride height and come pre-set to level your vehicle right out of the box. The DSC adjuster adds remarkable versatility and precise tuning with a simple twist of either two adjuster knobs, offering 10 separate low-speed and 12 high-speed compression levels, with a black anodized aluminum reservoir to increase cooling efficiency.
