Rear lift is achieved via a 4 Inch Block Kit with Add-A-Leaf, which helps freshen up worn factory leaf springs, adds approximately 1 inch of additional lift, includes new center pins, reduces axle wrap, and maintains factory payload weight ratings. Paired with NX2 Nitro Series shocks featuring nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends, 1-3/8-inch high-flow piston, self-lubricating seals, and silver powder coat finish.
This 6-inch lift kit from BDS Suspension is engineered for 1977–1987 Chevy and GMC 3/4 ton trucks and SUVs (K20 and K25), designed to improve 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 NX2 nitrogen-charged shocks. The rear configuration is available in either a high-strength block kit with add-a-leaf or full Glide-Ride leaf springs, both paired with longer U-bolts and a choice of NX2 Nitro or FOX 2.0 Performance Series shocks.
BDS Glide-Ride leaf springs use an exclusive triple-stage, multi-leaf progressive spring rate design that delivers a smooth ride under any load while providing flexibility throughout the full suspension cycle.
The 3/4 ton commonly came with a factory 56-inch eye-to-eye rear leaf spring. However, some were produced with a 52-inch rear spring. If ordering rear leaf springs, measure your factory rear spring before ordering. If equipped with a factory front sway bar, order the front sway bar shackle link kit listed in the accessories section. Some vehicles came with factory front dual shocks. If you wish to replace the factory duals, you must order the additional two auxiliary shocks in the options. Exhaust modification may be required to clear the front driveshaft. #001608 comes with OE-style rubber bushings installed.
