FULL PRODUCT ANNOUNCEMENT:
A few months back BDS Suspension introduced the 6.5″ coilover conversion high clearance systems, the latest performance option for the 2011-2017 Chevy Silverado HD and GMC Sierra/Denali HD trucks giving next level of performance and comfort to truck owners. These systems allow HD owners the ability to eliminate the rough riding traditional torsion bar suspension in favor of FOX 2.5 factory series remote DSC coilovers and combines them with the tried and true BDS high clearance IFS systems to truly unmatched performance on and offroad. For trucks already equipped with the non-coilover BDS 4.5″ and 6.5″ High Clearance Systems BDS is now offering an upgrade kit with all the components needed to convert over to the 6.5″ coilovers.
At the heart of this upgrade 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, 7/8″ hardened stainless steel shaft, FOX coil springs, black anodized machined 6061-T6 billet aluminum mounts and FOX’s DSC (dual speed compression) adjustment technology. The DSC adjustment allows for easy adjustment of the vehicle’s 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 “blue” high speed and “gold” 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 6.5″ of lift for optimal wheel travel. 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 FOX’s new performance upper control arms designed specifically for this system to integrate with the 2.5 coilovers. The arms are fabricated from large 1.5″ OD x .120-wall chromoly 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% improvement in wheel travel. The FOX upper control arms are finished in a durable black powdercoat and include a FOX branded 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 and 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.
