In addition to the 2", 4" and 6" lineup, BDS offers complete 8" lift systems. These 8" suspension systems offer even more tire clearance that and are designed to improved your truck's offroad capability. At the heart of these systems BDS utilizes the tried and true high-clearance IFS design that has made BDS the preferred suspension lift for late model GMs. This consists of a pair of newly designed 1/4" thick laser cut high clearance crossmembers and differential skid plate to reposition the lower arms while adding underbody protection and strength. These combined with the specially designed ductile iron replacement steering knuckles allow this system to maintain proper geometry for ESC system compatibility. Up front these kits use a multipoint differential relocation kit and to securely reposition the front differential to correct CV axle operating angle and allow use of the stock front driveshaft with the supplied boot spacer. Along with retaining the factory geometry, factory ride quality is maintained at the new height using a set of BDS branded top mounted strut spacers allowing for quick and easy installation. Rounding out the front of this kit are heavy duty steering tie rod ends to work with the new knuckle assemblies, longer sway bar links and sway bar drop brackets to correct operating angle, brake line brackets and a BDS front skid plate.
In the rear of this 8" lift system, the factory blocks are replaced with 6" fabricated blocks, add-a-leafs and longer u-bolts to lift and level the stance. These blocks are ultra strong, specially designed with an offset pin to re-center the axle along with an integrated bump stop wing to properly limit suspension compression. Also included, BDS supplies brake line brackets allow the use of factory brake lines and your choice of specially tuned NX2 gas or FOX 2.0 performance series gas shocks are supplied to round out the rear of the kits. These kits come finished in a durable textured black powdercoat, all hardware is provided along with step-by-step installation instructions. All BDS kits include Factory Protection Plus for the ultimate extended warranty to include BDS's No Fine Print Warranty, FMVSS No.126 (ESC System) compliance certification and a 5year-100mile drivetrain warranty to match the dealer. Improve the look and capability of your late model Chevy/GMC 1500 truck with this new 8" lift system from BDS Suspension.
