Rear lift is achieved via a 4-inch cast steel block kit with Add-A-Leaf, providing a level stance front to rear without replacing factory rear leaf springs. Shocks are upgraded to FOX 2.0 Performance Series: featuring a 2-inch impact extruded aluminum body, internal floating piston (IFP) monotube design, CNC machined 6061-T6 aluminum mounting ends, massive 5/8-inch hard chrome plated heat-treated alloy steel shaft, race-developed high-flow piston, application-specific valving, and a long-lasting clear anodized finish.
Overview
This 6-inch lift kit from BDS Suspension is designed for 1988–1991 Chevy and GMC 3/4 ton Suburbans (4WD), delivering improved stance, performance, and capability with clearance for up to 36-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.

- If equipped with a factory front sway bar, order the front sway bar shackle link kit listed in the accessories section.
