This BDS 6.5" suspension lift kit transforms your 2020-2025 Chevy Silverado and GMC Sierra 2500 HD with a FOX 2.5 Performance Elite coil-over conversion and clearance for up to 38" tires. It replaces the factory torsion bars and upgrades both upper and lower control arms, the uppers fabricated from 1.5" OD x .120-wall TIG-welded tubing and the lowers built from fully boxed, internally gusseted high-strength steel. BDS's high-clearance design pairs 1/4" steel crossmembers, multipiece differential relocation brackets, and heavy duty skid plates with CNC-machined ductile iron steering knuckles to correct steering geometry at ride height.

FOX 2.5 Performance Elite coil-overs come tuned and ready to bolt on, with a remote reservoir for added cooling and Dual Speed Compression Adjust offering 10 low-speed and 12 high-speed settings. The rear uses replacement lift blocks, a u-bolt flip kit for max clearance, and FOX 2.0 Performance shocks.

Notes

• Compatible with diesel models ONLY. Works with standard or AT4 diesel models.
• Will NOT work with AT4X or ZR2 models, lower control arm profile is different.
• For DRW models, use the w/ overload rear lift option.
• Requires frame bracket modification.
• Models with two-piece rear drive shafts will require a carrier bearing drop kit (BDS121612).
• Disassembly/assembly of the factory torsion bar system requires a special unloading tool. The GM specified tool # is CH48809.
• Coilover coil has a large amount of preload; a coil spring compressor must be used to remove the coil from the coilover. Failure to use a coil spring compressor may result in death or injury.
• Do not increase coilover preload.
• Factory 17-18" wheels cannot be reinstalled due to tie rod end interference; stock 20" wheels can be reinstalled with up to a 37x12.50 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.
