Take your 2020-2024 Chevy Silverado and GMC Sierra 2500 HD 4WD to the next level with this BDS 6.5" lift kit, with clearance for up to 38" tires. For maximum ground clearance, BDS uses a No Torsion Bar Drop System mounting the torsion bars directly to the top of the lower a-arm. Up front it uses torsion bar relocation brackets, 1/4" thick high-arched steel crossmembers, multipiece differential relocation brackets, and heavy duty skid plates, with CNC-machined ductile iron steering knuckles, sway bar drops, and stainless steel brake lines. The rear uses replacement lift blocks and u-bolts that retain ride quality and load capacity, brake line and ABS line relocation brackets, and a matching set of NX2 Nitro or FOX 2.0 Performance Series shocks.

Notes

• For DRW models, use the w/ overload rear lift option.
• Requires frame bracket modification.
• Torsion Bar Tool required to load/unload torsion bars. The GM specified tool is #CH48809.
• Models with two-piece rear driveshafts will require a carrier bearing drop kit.
• Factory 17-18 inch wheels cannot be reinstalled due to tie rod end interference; stock 20 inch 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, BDS recommends 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 inch lift height.
• Some minor trimming will be required with certain wheel/tire combinations (bottom edge of the inner fender shrouds and/or lower corner of front bumper valance). Deeper backspacing and shorter/narrower tires will reduce or eliminate trimming.
