Overview
Give your 2007-2018 Chevy Silverado or GMC Sierra 1500 equipped with a BDS 0 to 2-inch lift kit a race-winning technology upgrade to improve damping in any terrain with FOX Factory Series 2.5 Coil-Over shocks with Reservoir. 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.
