6.5 Inch Lift Kit | FOX 2.5 Coilover Conversion | Chevy Silverado or GMC Sierra 2500HD/3500HD (20-26) | Diesel

BDS is a game-changer for the performance of your 2020-2026 Chevy Silverado and GMC Sierra 2500 HD trucks with a 6.5-inch suspension lift kit and FOX 2.5-inch coilover conversion. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 38" tires. These kits feature proprietary FOX 2.5 coil-over shocks designed to bolt on performance, with increased travel and the ability to soak up the roughest terrain while maintaining smooth on-road comfort.

In addition to replacing the factory torsion bars, the upper and lower control arms are upgraded to improve strength and travel, and to accommodate the new coilovers. The new upper control arms are fabricated from large 1.5" OD x .120-wall tubing, fully TIG welded for the highest quality, strength, and durability. To complement the uppers, the new lower control arms are built from high-strength steel, fully boxed with internally gusseted.

This kit leverages BDS's proven high-clearance design to improve ground clearance, strength, and off-road protection, while correcting suspension and steering geometry for excellent on-road handling. Up front, the kit uses FOX 2.5 coilover shocks, heavy-duty tubular upper control arms, fully boxed and gusseted lower control arms, high-arched 1/4-inch-thick steel crossmembers, and a multipiece differential relocation bracket and heavy-duty skid plates for off-road protection. Steering geometry is corrected at the new taller ride height with CNC-machined ductile iron steering knuckles. These, combined with the provided sway bar links, bump stop extensions, stainless steel brake lines, CV spacers, supplied hardware, and more, provide a comprehensive front suspension lift ready for whatever you throw at it.

In the rear, BDS offers replacement lift blocks to lift and level that stance. The lift block installs in place of the stock block and retains ride quality and load capacity. Also for the rear is a U-bolt flip kit for max clearance and precision-tuned FOX 2.0 Performance Series shocks for ultimate off-road performance.

FOX Performance Elite

FOX 2.5 Performance Elite shocks deliver next-level performance for on-road and off-road comfort. Tuned and ready to install right out of the box, these bolt-on 2.5-inch diameter shocks are built for abuse and packed with race-proven technology. They include a remote reservoir for additional fluid capacity, keeping your shocks running cool so you can push the limits in rough terrain. The DSC adjuster adds remarkable versatility and precise tuning with a simple twist of either two adjuster knobs, offering 10 separate low-speed and 12 high-speed compression levels, with a black anodized aluminum reservoir to increase cooling efficiency.

HD Control Arms

Built for strength, performance, and increased travel, these control arms bolt in. The upper arms use 1.5" OD x .120-wall tubular construction with an indexed ball joint cup to correct the ball joint positioning, allowing additional down travel and camber adjustment. The new lower control arms are built from high-strength steel, fully boxed with internally gusseted. At the frame mounting ends, durometer-specific rubber bushings provide maintenance-free operation, while at the other end, quality greaseable ball joints offer smooth, quiet operation and superior durability. Arms are finished in a durable black powder coat with a billet aluminum dust cap ready for installation right out of the box.
