BDS 6.5 Inch Lift Kit with FOX 2.5 Coil-Over Conversion for 2020-2026 Chevy Silverado or GMC Sierra 2500HD/3500HD Diesel

Key Features

• FOX 2.5 Performance Elite coilovers with a remote reservoir for added fluid capacity and cooler operation, plus a DSC adjuster offering 10 low-speed and 12 high-speed compression settings for precise tuning across any terrain.
• Heavy-duty tubular upper control arms built from 1.5" OD x .120-wall tubing, fully TIG welded, with an indexed ball joint cup that corrects ball joint positioning for additional down travel and camber adjustment.
• Fully boxed, internally gusseted lower control arms made from high-strength steel, with maintenance-free durometer-specific rubber bushings and greaseable ball joints for smooth, durable operation.
• High-clearance design with no torsion bar drop to maximize ground clearance, supported by high-arched 1/4-inch-thick steel crossmembers.
• CNC-machined ductile iron steering knuckles that correct steering geometry at ride height and maintain ESC system compliance.
• HD skid plate system and multipoint differential relocation brackets to secure the front axle, improve CV angles, and add off-road protection.
• Rear lift blocks, U-bolt flip kit, and FOX 2.0 Performance Series shocks to level the stance, maximize clearance, and retain ride quality and load capacity.
• Factory Protection Plus drivetrain warranty included, with a durable black powder coat finish on the control arms for long-term corrosion resistance.

Fitment

This kit fits 2020-2026 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD trucks. It is compatible with diesel models ONLY, including standard and AT4 diesel configurations. Recommended tire and wheel setup is 37 x 12.5 tires on 20 x 9 wheels with 4.5" to 5.5" of backspacing (trimming may be required).

Important Notes

• Compatible with diesel models ONLY (standard or AT4 diesel).
• Models with two-piece rear driveshafts require a carrier bearing drop kit (BDS121612).
• For DRW models, use the w/ overload rear lift option.
• Requires frame bracket modification.
• Factory 17, 18, and 20" wheels cannot be reinstalled due to UCA and tie rod end interference.
• Disassembly and assembly of the factory torsion bar system requires a special unloading tool (GM tool #CH48809).
• The coilover coil carries a large amount of preload. A coil spring compressor MUST be used to remove the coil from the coilover; failure to do so may result in death or injury. Do not increase coilover preload.
• Some minor trimming may be required with certain wheel/tire combinations, typically the bottom edge of the inner fender shrouds and/or lower corner of the front bumper valance. Deeper backspacing and shorter/narrower tires reduce or eliminate trimming. Additional trimming tips are included in the instruction sheet.
• Vehicles regularly used in 4WD on the highway could potentially experience minor front driveline vibration. If this occurs, we recommend replacing the front driveshaft with a dual Cardan style driveshaft.
