  • Compatible with standard models as well as AT4 models.
  • Some minor trim will be required with certain wheel/tire combination. This is normal with most aftermarket tire/wheel fitment on Chevy/GM trucks. Trimming will normally included the bottom edge of the inner fender shrouds and/or lower corner of front bumper valance. As a rule of thumb, deeper backspacing and shorter/narrower tires will reduce/eliminate trimming required. Further trimming tips are included at the end of this instruction sheet.

These new lift systems offer comfortable handling and capability. While some companies build "kits" to fit larger tires, BDS Suspension prides itself in engineering complete suspension systems designed to take your vehicle's performance to the next level while retaining OE-level functionality.

3" Lift Kits: Designed for simple bolt-on installation, these 3" lift kits allow clearance for up to 35" tires. At the heart of these systems are a pair of heavy duty tubular upper control arms (UCAs) designed for improve strength and allow for additional suspension travel. These new control arms are built from thick wall 1.5" DOM tubing, and use an indexed ball joint cup to reposition the upper ball joints. These arms come fully assembled right out of the box with high quality greaseable ball joints and rubber bushings for long life, quiet operation and superior corrosion resistance over uniballs and heims. Along with the control arms, a pair of indexed cast steel torsion bar keys are supplied up front to lift vehicle. A small differential relocation kit is supplied to correct CV axle operating angles without effecting ground clearance. To eliminate sway bar interference, a pair of sway bar relocation brackets is used which maintains proper operating angle. In the rear a 2" block and u-bolt kit is used to create a level to slightly tail high stance when unloaded. Rounding out these kits are a pair of specially tuned FOX 2.0 performance series IFP shocks ready to soak up the terrain.

5"/6.5" Lift Kits: At the heart of these 5"/6.5" lift systems, BDS utilizes a pair of 1/4" thick laser cut high clearance crossmembers to maximize clearance and provide a solid mounting point for the OE lower control arms. These paired with the heavy duty front skid plate create a rigid subframe while adding protection for vital steering and driveline components. In place of the factory steering knuckles are a pair of specially designed ductile iron replacement steering knuckles are supplied to maintain proper steering geometry for ESC system compatibility. The front differential is repositioned with BDS's multipoint relocation bracket system to secure the front differential to keep CV axle angles at a minimum. To help maximize clearance a pair of specially designed torsion bar relocations brackets are supplied to mount to the lower control arms to retain the factory high clearance frame mounted crossmember. A pair of BDS-branded sway bar drop brackets used to correct the operating angle of the factory sway bar along with extended length braided stainless steel brake lines.
