BDS Lift Kit 2.5in Coilover Conversion Kit w/Overload (11-19 GMC/Chevrolet Sierra/Silverado HD)

For years now, Chevy Silverado HD and GMC Sierra/Denali HD owners have been limited to the traditional torsion bar system suspension options. BDS Suspension is excited to add next level technology for improved performance. Adding to the current 4.5in and 6.5in high clearance no torsion bar drop systems offered for 2011+ Chevy/GMC HD trucks, BDS is now shipping 2-3in coilover conversion systems for superior ride quality and performance over any terrain. These new coilover systems have been engineered and tested for improved comfort, fade free performance, and increased suspension travel. The new 2-3in coilover system is a game changer for HD performance. At the heart of the system is a pair of FOX 2.5 Factory Series Coilover with remote DSC reservoir. These coilovers offer vastly superior dampening for impressive capability to soak up the harshest terrains offroad while offering comfort on your daily commute .These FOX coilovers feature a smooth bore and honed seamless alloy body, 7/8in hardened stainless steel shaft, FOX coil springs, black anodized machined 6061-T6 billet aluminum mounts and FOXfts DSC (dual speed compression) adjustment technology. DSC is the next big thing in suspension performance allowing for easy adjustment of the vehiclefts suspension compression dampening to dial in the ideal ride performance to soak up the bumps, both large and small. The DSC has 12 adjustment points for the high speed compression as well as 10 adjustment points for the low speed compression allowing you to make large or small changes to further improve your performance. Adjustments can be made by simply twisting the inbluein high speed and ingoldin low speed compression knobs located on the end of the remote reservoir of the FOX 2.5 coilovers. No tools or shop adjustments needed, allowing you to tune the suspension out on the trail. The coilovers come fully assembled, preset for 2.5in of lift for optimal wheel travel, but can be adjusted between 2-3in of lift with the use of (#129600) spanner wrench. To mount the coilovers BDS supplies a bolt-on bracket that installs on the frame in the shock mount location. A weld-in support gusset is used to reinforce the upper mount, however still allows the kit to be completely reversible if the owner ever chooses to revert back to the torsion bar style suspension and upgrade the suspension on another truck. In addition to replacing the factory torsion bars, the upper and lower control arms are upgraded to improved strength, travel, and accommodate the new coilovers. The uppers are new performance upper control arms designed specifically for this system to integrate with the 2.5 coilovers. The arms are fabricated from large 1.5in OD x .120-wall tubing, fully TIG welded for the highest quality, strength and durability. The arms utilize premium Moog brand ball joints and factory style rubber bushings for smooth, quiet operation and superior durability when compared to arms with uni-balls, poly bushings or heims. The ball joint cups are repositioned for optimal performance allowing a 30 percent improvement in wheel travel. The upper control arms are finished in a durable black powdercoat and include a billet aluminum ball joint dust cap. The control arms come fully assembled for easy install right out of the box. To compliment the uppers, the new lower control arms are built from high strength steel, fully boxed with internally gusseted. These lower arms integrate new reinforced lower coilover mounts and similar to the uppers use durometer specific rubber bushings at the frame mount and high quality Moog ball joints at the knuckle mount for quiet, low maintenance operation. Rounding out the front suspension BDS supplies front differential relocation to correct CV axle operating angle to optimize CV performance. The relocation hardware installs easily with no differential modification needed while also allowing the reinstallation of the factory skid plate. Longer sway bar links are also included and bolt directly in place of the factory links to correct sway bar operating angle. In the rear, BDS offers a simple block and u-bolt kit that retains ride quality and full use of the factory overload spring (if equipped). The rear comes standard with precision tuned FOX 2.0 IFP gas shocks and is available with optional FOX factory series 2.5 reservoir shocks. Additional options and accessories are in development; stay tuned for more information as new products are released.
