4.5"/6.5" Coilover Conversion Systems - Ever since the launch of BDS Suspension's coilover conversion systems for late model (2011+) Chevy/GMC HD trucks there has been a huge demand in the aftermarket for similar options for the earlier 2001-2010 HD trucks and SUVs. BDS answers that call with new 4.5" and 6.5" high clearance coilover conversion systems engineered for next level performance. These kits build on the BDS high clearance system technology offering increased ground clearance and improved suspension, steering and driveline geometry and pairs it with the race proven pedigree of FOX 2.5 factory series coilovers to soak up the harshest terrain and on-road comfort.
At the heart of these systems you'll find the FOX 2.5 factory series coilover with remote DSC reservoir. These 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 damping 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 on any terrain. 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 either 4.5" or 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 control arms (UCA) are upgraded to improved strength, travel, and accommodate the new coilovers. The uppers are new performance series 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 tubing, fully welded and gusseted 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 for improved suspension travel. These 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. The factory cast steel lower control arms are retained with the addition of a robust lower coilover mounting bracket.
Along with the coilover conversion, these 4.5"/6.5" coilover systems includes a pair of one-piece laser cut high clearance crossmembers, CNC machined ductile iron steering knuckles to correct steering angles, heavy duty front skid plate and differential skid plate to increase protection, multipoint differential relocation brackets to secure differential and correct CV axle angles, CV spacers, and longer sway bar links. In the rear, these kits are designed to level the stance to the front. BDS offers a 3" rear block kit for the 4.5" systems while the 6.5" systems are offered with your choice of 5" rear block kit or replacement GlideRide leaf springs. The leaf springs have additional arch built into the 5-leaf pack and integrates an overload leaf into the pack to assist with hauling heavy loads. All kits include black e-coated u-bolts along with FOX 2.0 performance series IFP shocks to round out the package ready to offer impressive performance wherever your the adventures lead you. The 4.5" system are designed for fitment of 35" tires while the 6.5" kit allows fitment of 35-37" tires.
