For maximum ground clearance, BDS designed a No Torsion Bar Drop System where the torsion bars are mounted directly to the top of the lower a-arm eliminating the need to drop the torsion bar cross-member. Designed to improve the stance, performance, and capability; this kit includes everything necessary to set your truck up right with clearance for up to 38" tires.

Part Number: BDS1825FPE

Tire Fitment: 

• 38 x 13.5 with 20 x 9 and 6.18 in. Backspace
• 37 x 12.5 with 20 x 9 and 4.5 in. Backspace

• For DRW models, use the w/ overload rear lift option
• Requires frame bracket modification.
• Torsion Bar Tool required to load/unload torsion bars
• 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 frequently 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 than the tested 6.5" lift height.
• Some minor trim will be required with certain wheel/tire combinations. This is normal with most aftermarket tire/wheel fitment on Chevy/GM trucks. Trimming will normally include the bottom edge of the inner fender shrouds and/or the lower corner of the 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.
• Will NOT work with AT4X or ZR2 models, lower control arm profile is different
