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

BDS sets a new standard for the 2001-2010 Chevy Silverado and GMC Sierra 2500 HD trucks with their 4.5-inch suspension lift kit featuring FOX 2.5 Coil-Over conversion. Engineered to enhance stance, performance, and capability, this comprehensive kit provides everything needed to equip your truck for optimal performance, with clearance for up to 33" tires.

At the core of this kit are the proprietary FOX 2.5 coil-over shocks, designed specifically to deliver outstanding performance both on and off the road. Tuned and ready to install out of the box, these 2.5-inch diameter coil-overs feature race-proven technology and a remote reservoir for increased fluid capacity, ensuring reliable operation even in rugged terrain.

BDS's signature high-clearance design is utilized throughout, maximizing ground clearance, strength, and off-road protection while also correcting suspension and steering geometry for superior on-road handling. Up front, the kit integrates FOX 2.5 coil-over shocks, heavy-duty tubular upper control arms, and high-arched 1/4-inch thick steel crossmembers. These components are complemented by multipiece differential relocation brackets and heavy-duty skid plates, providing comprehensive off-road protection. Additionally, steering geometry is optimized at the increased ride height with CNC-machined ductile iron steering knuckles.

Included in the kit are sway bar drops, bump stop extensions, brake line brackets, CV spacers, and all necessary hardware, ensuring a complete front suspension lift solution.

For the rear, BDS offers both replacement lift block and full Glide-Ride leaf spring options to achieve the desired lift and level stance. The lift block maintains ride quality and load capacity, while precision-tuned FOX 2.0 Performance Series shocks ensure optimal rear suspension performance.

Experience unmatched strength and performance with BDS's heavy-duty upper control arms. These arms feature 1.5" OD x .120-wall tubular construction with indexed ball joint cups for additional down travel and camber adjustment. Durometer-specific rubber bushings at the frame mounting ends ensure maintenance-free operation, while quality greaseable ball joints at the other end provide smooth, quiet operation and superior durability. Finished in a durable black powder coat with billet aluminum dust caps, these control arms are ready for installation right out of the box.

Maximize ground clearance with BDS's heavy-duty 1/4-inch thick laser-cut crossmembers, which are paired with a front skid plate system for added protection and structural integrity.
