2020-2025 GM HD 6.5" FOX 2.5 Performance Elite Conversion Kit (BDS792FPE)

Step up your 2020-2024 Chevy Silverado and GMC Sierra 2500 HD with this BDS 6.5" suspension lift kit with FOX 2.5 coil-over conversion, with clearance for up to 38" tires. It replaces the factory torsion bars and upgrades to fully TIG-welded 1.5" OD x .120-wall tubular upper control arms and fully boxed, internally gusseted lower arms. Up front are the FOX 2.5 coil-overs, high-arched 1/4" steel crossmembers, multipiece differential relocation brackets, HD skid plates, CNC-machined ductile iron steering knuckles, sway bar links, bump stop extensions, stainless brake lines and CV spacers. The rear uses replacement lift blocks, a u-bolt flip kit and FOX 2.0 Performance Series shocks. The DSC adjuster offers 10 low-speed and 12 high-speed compression levels.

Notes

• Models with two-piece rear driveshafts will require a carrier bearing drop kit (BDS121612).
• Requires frame bracket modification.
• Disassembly/assembly of the factory torsion bar system requires a special unloading tool; the GM specified tool is CH48809.
• Compatible with diesel models ONLY. Works with standard or AT4 diesel models.
• Some minor trim 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.
• 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.
• 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.
• Coilover coil has a large amount of preload; a coil spring compressor must be used to remove the coil. Failure to use one may result in death or injury.
• Do not increase coilover preload.
• For DRW models, use the w/ overload rear lift option.
• Will NOT work with AT4X or ZR2 models; lower control arm profile is different.
