The BDS Suspension BDS772FDSC / 755FDSC 3.5-inch suspension lift kit for the GMC Sierra 1500 is a premium lift kit designed to fit up to 35-inch diameter tires for a great off-road look. This is done without sacrificing ride quality or handling while improving off-road performance.

This premium quality suspension lift kit is built around Fox 2.5 Performance Elite Series remote reservoir DSC (dual speed compression) coilovers that provide optimal performance and direct bolt-in replacement for the factory struts. These adjustable coilovers allow for easy, tool-free adjustment of high-speed and low-speed compression adjustment settings to further dial in the damping to the terrain and ride preferences. Also included are heavy-duty upper control arms designed for high strength and improved suspension travel. These arms use 1.5-inch DOM tubing and an indexed ball joint cup to allow for more suspension droop travel.

The rear end is lifted with rear axle blocks and extended ubolts.

Fox 2.0 Performance Series rear shocks are included, or you can upgrade to the high-end Fox 2.5 Performance Elite Series DSC remote reservoir shocks.
