BDS Suspension 6" Lift Kit for Chevrolet/GMC 4WD Suburban, Tahoe, Yukon, and Yukon XL 1500 1/2 ton SUVs.
This 6" IFS lift kit offers improved performance over any terrain, improved offroad protection, and enhanced on-road comfort. At the core of this 6" lift system is 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. 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, BDS supplies a pair of high pressure gas struts for improved performance and ride quality. 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 a pair of a 5" ProRide coil springs are supplied to lift and level the stance. These offer improve 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 your choice of BDS- NX2 series gas shocks or FOX 2.0 IFP performance gas shocks.
This kit allows for up to 35x12.50 tires to be installed. This kit is available for all three factory control arm configurations (cast steel, stamped steel, and aluminum) so be sure to verify your factory control arm type before ordering.

No Fine Print Warranty
BDS stands behind its products and that’s evident by their No Fine Print Warranty. This no-BS warranty protects the original purchaser against breakage, bending, sagging, or any other usage failure. This “no fine print” lifetime replacement warranty extends to cover all BDS hard parts as well as bushings. Exclusions would be product finish and wearable items such as shock/stabilizer cylinders, tie rod ends and ball joints that would fall under the separate Limited Lifetime Warranty policy. Beginning February 1, 2020 all new kit purchases include the No Fine Print Warranty on bushings.

Limited Lifetime Warranty (for wearable items)
Wearable items include shock/steering stabilizer cylinders, ball joints and tie rod ends. BDS Suspension Co. warrants to the original retail purchaser that its these wearable parts are free from defects in material and workmanship for so long as they own the vehicle. Excluded from this warranty are the finish of the product. Defects in material and workmanship do not include such things as dented cylinders or bent rods caused by obvious side impact, rust or corrosion. A shock absorber is a wear item and over time will experience diminished damping resistance due to normal component wear. This is not a defect in material or workmanship and is therefore not warrantable.
