2014-2018 GM 1500 4wd 6"w/Spg Cast Steel DSC

BDS steps up the performance and capability of the 2014-2018 Chevy Silverado and GMC Sierra 1500 trucks with 6-inch coil-over suspension lift kits. These kits feature proprietary FOX 2.5 coil-over shocks designed specifically to bolt-on performance for increased travel and the ability to soak up the roughest terrain along with smooth on-road comfort.

This kit takes advantage of BDS's tried and true high-clearance design for improved ground clearance, strength, and offroad protection while correcting suspension and steering geometry for great on-road handling characteristics.

Up front, the kit utilizes high-arched 1/4-inch thick steel crossmembers along with a multipiece differential relocation brackets and heavy duty skid plates built for offroad protection. Steering geometry is corrected at the new taller ride height with CNC-machined ductile iron steering knuckles and replacement tie rod ends allowing for ESC system compatibility.

These combined with the provided sway bar links, bump stop extensions, brake line brackets, CV spacers, supplied hardware and more provide a comprehensive front suspension lift ready for whatever you throw at it.

In the rear BDS offers both replacement lift block and full Glide-Ride leaf spring options to lift and level that stance. The lift block installs in place of the stock block and retains ride quality and load capacity. Also for the rear are new u-bolts, brake line brackets and FOX 2.0 Performance Series shocks.

FOX 2.5 Coil-Overs

FOX 2.5 coil-overs offer next level performance for on-road comfort and off-road comfort capability. Tuned and ready to install right out of the box, these bolt-on 2.5-inch diameter coil-overs are built for abuse and packed with race-proven technology. They include a remote reservoir for additional fluid capacity to keep your shocks running cool so you can push the limits in the rough terrain.

Dual Speed Compression Adjust Adjustment

FOX 2.5 coil-overs are available with optional Dual Speed Compression Adjust (dual speed compression) adjustment to tune the high-speed and low-speed compression damping allowing for added control on-road with the ability to easily dial in more aggressive damping offroad. Tuning is a simple twist of the two clearly defined knobs with immediate feedback to dial it in for any terrain.
