4" Coilover Systems: BDS Suspension ups the ante offering next level performance for Chevy/GMC SUVs. Designed for improved performance, drivability and offroad capability these 4" performance coilover systems build on the tried and true BDS high clearance design adding FOX 2.5 remote reservoir coilovers and 2.0 rear IFP shocks. The kits utilize a pair of 1/4" steel high clearance crossmembers and 3-piece skid plate system to reposition the lower arms and add protection of vital drivetrain components. These combined with the CNC machined ductile iron replacement steering knuckles creates a solid subframe to correct suspension and steering geometry for compatibility with the factory installed ESC system. BDS offers these kits for 2007-2014 models as well as kits compatible with 2015-2018 SUVs equipped with factory cast steel, factory stamped steel, and factory aluminum control arms so be sure to check before ordering. Up front the kits use a multipoint differential relocation kit and CV spacers to securely reposition the front differential to correct CV axle angle and allow for the use of the stock front driveshaft. In place of the stock struts, a pair of FOX 2.5 remote reservoir coilover are supplied to bolt in place along with a reservoir mount. Optional DSC coilover are available as well to offer high-speed and low-speed compression adjustment to dial in ride quality and performance on any terrain (more info on DSC below). Also included for the front are heavy duty tie rod ends, longer sway bar links, and brake line brackets. In the rear this 4" lift system a pair of a 2" or 3" coil spacers are available (3" only for '15+ SUVs) to lift and level the stance. A track bar relocation bracket and support brace to recenter the rear axle, along with longer sway bar links, bump stop extensions and FOX 2.0 IFP performance gas shocks. This kit allows for up to 33x12.50 tires to be installed.

6" IFS Lift Kits: The 4" and 6" IFS systems share the high clearance design for improved performance over any terrain, improved offroad protection, and enhanced on-road comfort. At the core of these 6" lift systems are a pair of 1/4" steel high clearance crossmembers and full width modular differential skid plate to reposition the lower arms and add protection of vital drivetrain components. These combined with the CNC machined ductile iron replacement steering knuckles creates a solid subframe and correct suspension and steering geometry to be compatible with the factory installed ESC system. Kits are offered for all three factory control arm configurations, cast steel, stamped steel, and aluminum; be sure to check your vehicle before ordering. Differential relocation brackets and CV spacers are used to correct the front axle positioning for stock-like CV axle angles and to retain use of the factory front driveshaft. In place of the stock struts, a pair of FOX 2.5 remote reservoir coilover are supplied to bolt in place along with a reservoir mount. Optional DSC coilover are available as well to offer high-speed and low-speed compression adjustment to dial in ride quality and performance on any terrain (more info on DSC below). Rounding out the front kit are a pair of replacement tie rod ends, longer sway bar links, brake line brackets, and a front laser cut BDS skid plate. In the rear these of this 6" lift kit a pair of a 5" ProRide coil springs are supplied to lift and level the stance. These offer improved offroad performance and more travel from the rear suspension. To correct the rear suspension geometry with the taller coils installed a pair of heavy duty adjustable upper control arms are supplied along with a track bar relocation bracket and support brace and longer sway bar links. Also included are a pair of bump stop extensions and FOX 2.0 IFP performance gas shocks. This kit allows for up to 35x12.50 tires to be installed.

DSC Option: DSC (dual speed compression) adjustment technology is builds on the racing pedigree of the FOX 2.5 remote reservoir coilovers adding easy tuning of the vehicle’s suspension compression dampening to dial in the ideal ride performance to soak up the bumps, both large and small. The DSC has 12 adjustment points for the high-speed compression as well as 10 adjustment points for the low-speed compression allowing you to make large or small changes to further improve your performance for your particular needs. Adjustments can be made by simply twisting the "blue" high speed and "gold" low speed compression knobs located on the end of the remote reservoir of the FOX 2.5 coilovers. No tools or shop adjustments needed, allowing you to tune the suspension out on the trail. The coilovers come fully assembled, preset for 4" or 6" of lift right out of the box. Preload adjustments can be made using the #129600 spanner wrench available separately.
