2020-2025 GM HD 5" Lift Kit with FOX 2.0 Performance Shocks (BDS766FS)

Take your 2020-2025 Chevy Silverado and GMC Sierra 2500 HD 4WD to the next level with this BDS 5" lift kit, with clearance for up to 37" tires. BDS uses a No Torsion Bar Drop System, mounting the torsion bars directly to the top of the lower a-arm to maximize ground clearance. The high-clearance front pairs torsion bar relocation brackets, 1/4" steel crossmembers, multipiece differential relocation brackets, heavy duty skid plates, and CNC-machined ductile iron steering knuckles with sway bar drops and stainless steel brake lines. The rear uses replacement lift blocks and u-bolts plus brake and ABS line relocation brackets, finished with a matching set of NX2 Nitro or FOX 2.0 Performance shocks.

Notes

• Will NOT work with AT4X or ZR2 models, lower control arm profile is different.
• 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" wheels cannot be reinstalled due to tie rod end interference; stock 20" wheels can be reinstalled with up to a 35x12.50 tire.
• Some minor trimming will be required with certain wheel/tire combinations, normally the 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.
• Vehicles used in 4WD on the highway regularly could experience a minor front driveline vibration; if this occurs we recommend replacing the front driveshaft with a dual Cardan style driveshaft.
• Determine if your truck was manufactured with or without top-mounted overload springs on the rear leaf springs.
