Improve the style and handling of your 1977-1987 Chevy and GMC 1/2 ton truck or SUV with this 6-inch lift kit from BDS Suspension. Designed to improve stance, performance, and capability of the K5 Blazer, K10 and K15, this kit includes everything necessary to set your truck up right with clearance for up to 35 inch tires.
Up front the lift kit includes Glide-Ride leaf springs, 4 inch steering arm for steering correction, brake line brackets and precision tuned NX2 nitrogen charged shocks. In the rear this kit utilizes a high-strength lift block, longer u-bolts and a matching set of NX2 Nitro shocks.
Glide-Ride Leaf SpringsBuilt to outperform, BDS engineered the Glide-Ride leaf springs into a multi-leaf progressive spring rate design that provides a smooth ride with any load. This is accomplished with an exclusive triple-stage leaf spring design. Upgrading to BDS Glide-Ride leaf springs will provide flexibility throughout the suspension cycle.
