2020-2025 GM HD 5" Lift Kit with NX2 Nitro Shocks (BDS766H)

Take your 2020-2024 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. For maximum ground clearance BDS uses a No Torsion Bar Drop design where the torsion bars mount directly to the top of the lower a-arm. Up front are torsion bar relocation brackets, high-arched 1/4" steel crossmembers, multipiece differential relocation brackets, HD skid plates, CNC-machined ductile iron steering knuckles, sway bar drops and stainless brake lines. The rear uses replacement lift blocks, u-bolts, brake line and ABS relocation brackets, and NX2 Nitro or FOX 2.0 Performance Series shocks.

Notes

• 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.
• Vehicles regularly used in 4WD on the highway could experience a minor front driveline vibration; if so, replace the front driveshaft with a dual Cardan style driveshaft.
• Some minor trimming will be required with certain wheel/tire combinations (inner fender shrouds and/or lower corner of 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.
• Determine if your truck was manufactured with or without top-mounted overload springs on the rear leaf springs.
