At the heart of this new 5" 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 maximaze clearance a pair of 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. Rounding out the front of this kit are FOX 2.0 performance series IFP shocks.

In the rear of this 5" lift system 3" lift blocks and longer u-bolts to lift and level the stance. Also included, BDS supplies brake line and ABS line relocation brackets allow the use of factory brake lines. Lastly a matching set of FOX 2.0 performance series IFP shocks are supplied to compliment the front setup.

Installation Instructions

766FS Instructions

Product Video

• Torsion Bar Tool required to load/unload the torsion bars
• Requires frame bracket modification
• Models with two-piece rear driveshafts will require a carrier bearing drop kit
• Factory 17-18" wheels cannot be reinstalled due to tie rod end interference, stock 20" wheels can be reinstalled with up to a 35x12.50 tire
• In some cases vehicles used in 4WD on the highway regularly could potentially experience a minor front driveline vibration. If this occurs we recommend replacing the front driveshaft with a dual Cardan style driveshaft
• Do not install this suspension system in conjunction with any type of torsion bar lift keys to achieve more that tested 6.5" lift height
• U-bolts will not work vehicles equipped with top-mounted overload springs or add-a-leafs.
• Compatible with gas or diesel models
• 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.
