Fits: 2001 thru 2010 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7/LLY/LBZ/LMM Duramax Diesel 

The coilover kit that all the 01-10 Duramax trucks have been waiting for is finally here. This system builds on the BDS high clearance system design offering more ground clearance, correct suspension, steering, and driveline geometry. The kit is paired 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 are upgraded to improved strength, travel, and accommodate the new coilovers. The uppers are a new performance series, designed specifically for this system to integrate with the 2.5 Fox Coilovers. The upper control arms are fabricated from large 1.5" 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 6.5" lift 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 5" rear block and u-bolt kit(Glide-Ride Leaf Springs optional) 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 kit will fit 35-37" tires, trimming may be required.
