Upgrade the performance and capability of your 2015-2019 Chevy Suburban, or Tahoe and GMC Yukon 1500 with 4-inch coil-over suspension lift kit by BDS. 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. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 33" tires
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 full length replacement strut shocks, 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. These combined with the provided sway bar drops, 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 coil spring spacers to properly level the vehicle. Also for the rear are precision tuned NX2 Nitro or premium 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.
DSC Adjustment
FOX 2.5 coil-overs are available with optional DSC (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.
