BDS is now providing 2-3" 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. 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, 7/8" 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 coilovers come fully assembled, preset for 2.5'' of lift for optimal wheel travel, but can be adjusted between 2-3" 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 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 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.

Important Kit Notes

  • Minor metal trimming may be required with 35x12.50R20 on 20x9 w/5-5.5" BS
  • Requires minor welding
  • Coilovers are preset for DIESEL engine models. The use of the coilovers on GAS engine models is not recommended due to providing too much lift. Available preload adjustment is typically not enough to achieve desired ride height.
  • Factory 17" and 18" wheels cannot be reinstalled. Factory 20" wheels can be reused with stock tire size. See instructions for detailed wheel/tire fitment notes.
  • Dually Models will require aftermarket 20" wheels with a max tire size of 285/60/20.
