6.5 Inch Lift Kit | FOX 2.5 Coilover Conversion | Chevy Silverado or GMC Sierra 2500HD/3500HD (11-19) | Diesel

BDS is a game-changer for the performance of your 2011-2019 Chevy Silverado and GMC Sierra 2500/3500 HD trucks, with a 6.5-inch suspension lift kit and FOX 2.5 Performance Elite 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 37" tires. These kits feature proprietary FOX 2.5 Performance Elite coil-over shocks designed to bolt on performance, with increased travel and the ability to soak up the roughest terrain, along with 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 coil-overs. 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 follows BDS's engineering standard 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, and multipiece differential relocation brackets to maintain correct CV angles. These, combined with the provided sway bar links, 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 or Performance Elite Series 2.5” shocks for ultimate off-road performance.

FOX 2.5 Performance Elite Coil-Overs

FOX Performance Elite 2.5 coil-overs deliver next-level performance and on-road and off-road comfort. Tuned and ready to install right out of the box, these bolt-on 2.5-inch diameter coilovers are built for abuse and packed with race-proven technology. They include a remote reservoir for additional fluid capacity, helping keep your shocks running cool so you can push the limits in rough terrain.

DSC Adjustment

FOX Performance Elite 2.5 coil-overs come standard with DSC (dual-speed compression) adjustment to tune high-speed and low-speed compression damping, providing added on-road control and making it easy to dial in more aggressive off-road damping. Tuning is a simple twist of the two clearly defined knobs with immediate feedback to dial it in for any terrain.

HD Control Arms

Built for strength, performance, and increased travel, these control arms are ready to 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.
