2020-2025 GM HD 6.5" Lift Kit (BDS1825FPE)

BDS 6.5" lift for the 2020-2025 Chevy Silverado and GMC Sierra 2500 HD 4WD with clearance for up to 38" tires. For maximum ground clearance, BDS uses a No Torsion Bar Drop System that mounts the torsion bars directly to the top of the lower a-arm, eliminating the torsion bar cross-member drop. Up front it uses torsion bar relocation brackets, 1/4" thick high-arched steel crossmembers, multipiece differential relocation brackets, heavy duty skid plates, and CNC-machined ductile iron steering knuckles. In the rear it uses replacement lift blocks and u-bolts, brake line and ABS line relocation brackets, and a matching set of NX2 Nitro or FOX 2.0 Performance shocks. The FOX 2.5 shocks add a remote reservoir and Dual Speed Compression Adjust with 10 low-speed and 12 high-speed settings.

Notes

• 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 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.
• Vehicles used in 4WD on the highway frequently could experience a minor front driveline vibration; if this occurs, replace the front driveshaft with a dual Cardan style driveshaft.
• Do not install this system in conjunction with any type of torsion bar lift keys to achieve more than the tested 6.5 inch lift height.
• Some minor trim may be required with certain wheel/tire combinations (inner fender shrouds and/or lower corner of the front bumper valance). Deeper backspacing and shorter/narrower tires reduce trimming.
• Will NOT work with AT4X or ZR2 models; lower control arm profile is different.
