This system builds on the BDS high clearance system design offering more ground clearance or correct suspension, steer, driveline geometry and pairs it with the race proven pedigree of FOX 2.5 factory series coilovers to soak up the harshest terrain while still offering comfort and control for your daily commute. The coilovers come pretuned and ready to install right out of the box featuring dual speed compression (DSC) adjusters on the reservoir for easy tuning of the high-speed and low-speed compression damping without the need for special tools. To mount the coilovers BDS supplies a bolt-on bracket that installs on the frame in the shock mount location along with a weld-in support gusset is used to reinforce the upper mount.
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 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" coilover systems include 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 a 3" rear block and u-bolt kit is used to level the stance while a set of FOX 2.0 performance series IFP shocks are supplied to pair with the front coilovers for impressive performance wherever your the adventures lead you.
This highly customizable kit gives you the choices you need to build your rig your way. Standard or narrow track knuckle kits, gas shocks, and dual steering stabilizers are just a few of the options and upgrades available for this 4-1/2" Chevy/GMC suspension lift kit.
