2020-2025 GM HD 6.5" FOX 2.5 Coilover Kit with FOX 2.0 Rear, Diesel, Block, Overload (BDS756FPE)

This BDS 6.5" lift kit with FOX 2.5 Coil-Over conversion is a game changer for your 2020-2025 Chevy Silverado / GMC Sierra 2500 HD, with clearance for up to 38" tires. In addition to replacing the factory torsion bars, the control arms are upgraded: tubular uppers from 1.5" OD x .120-wall fully TIG-welded tubing with an indexed ball joint cup, and fully boxed, internally gusseted high-strength steel lowers. Up front it also runs high-arched 1/4" steel crossmembers, multipiece differential relocation brackets, HD skid plates and CNC-machined ductile iron steering knuckles. The rear uses replacement lift blocks, a u-bolt flip kit for max clearance and FOX 2.0 Performance shocks. The bolt-on FOX 2.5 remote-reservoir shocks are race-proven and tune out of the box, with a Dual Speed Compression adjuster offering 10 low-speed and 12 high-speed compression levels.

Notes

• Models with two-piece rear drive shafts will require a carrier bearing drop kit (BDS121612).
• Requires frame bracket modification.
• Disassembly/assembly of the factory torsion bar system requires the GM-specified unloading tool #CH48809.
• Compatible with diesel models ONLY. Works with standard or AT4 diesel models.
• Some minor trim will be required with certain wheel/tire combinations (typically the bottom edge of the inner fender shrouds and/or lower corner of front bumper valance). Deeper backspacing and shorter/narrower tires reduce trimming.
• 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 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 from the coilover. 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).
