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 FOXs DSC (dual speed compression) adjustment technology. The DSC adjustment allows for easy adjustment of the vehicles 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 6.5in 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 BDSft 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 BDS 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.
