Overview
This 4-inch lift kit from BDS Suspension is designed for 1988–1991 Chevy and GMC 3/4 ton Trucks and Suburbans (4WD). The kit improves stance, performance, and capability while providing clearance for up to 35-inch tires. Up front, the kit includes Glide-Ride leaf springs, a 4-inch steering arm for steering correction, brake line brackets, and precision-tuned shocks. In the rear, the kit utilizes a high-strength lift block, longer U-bolts, and a matching set of shocks. Rear lift options include a block kit, a block kit with add-a-leaf, or full replacement Glide-Ride leaf springs.
