Elevate your Colorado ZR2's off-road capabilities while preserving the factory DSSV shocks with the BDS 4-inch suspension lift kit. Engineered to enhance stance, performance, and versatility, this kit equips your ZR2 with clearance for up to 35" tires, ensuring you're ready to tackle any terrain.

The kit features specially designed strut spacers to accurately position the DSSV coilovers, maintaining ride height and ensuring adequate clearance throughout suspension travel. Built on BDS's proven high-clearance design principles, this kit improves ground clearance, strength, and off-road protection while addressing suspension and steering geometry for exceptional on-road handling.

At the front, the kit incorporates top-mounted strut spacers, robust 1/4-inch thick steel crossmembers, multipiece differential relocation brackets, and heavy-duty skid plates for enhanced off-road protection. Corrected steering geometry at the increased ride height is achieved through CNC-machined ductile iron steering knuckles and replacement tie rod ends, ensuring compatibility with the ESC system.

Included components like sway bar links, bump stop extensions, CV spacers, and comprehensive hardware round out the package, providing a complete front suspension lift solution capable of handling any challenge you encounter off-road.

Benefit from enhanced ground clearance with BDS's heavy-duty 1/4-inch thick laser-cut crossmembers, meticulously designed for a precise fit. These crossmembers, coupled with a front skid plate system, combine to form a robust subframe, providing both structural integrity and additional protection.

Ensure optimal steering performance at the increased ride height with BDS's heavy-duty steering knuckles. Crafted from high-strength CNC-machined ductile cast iron, these steering knuckles are engineered to work seamlessly with replacement tie rod ends, maintaining proper steering angles for functionality and ESC compatibility.
