Description

Rear lift is achieved with Glide-Ride Rear Leaf Springs — a multi-leaf progressive spring rate design that helps freshen up old worn-out factory leaf springs, maintains factory payload weight ratings, and eliminates the need for a lift block. Paired with NX2 Nitro Series shocks featuring a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends, a 1-3/8-inch high-flow piston, self-lubricating seals, and a silver powder coat finish.

Overview

This 4-inch lift kit from BDS Suspension is designed for 1977–1987 Chevy and GMC 1/2 ton trucks and SUVs (K5 Blazer, K10, K15) to improve stance, performance, and capability. The kit includes everything necessary for a complete installation and provides 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 uses a high-strength lift block, longer u-bolts, and a matching set of shocks — with rear leaf spring options available depending on the selected configuration.

BDS Glide-Ride leaf springs use an exclusive triple-stage, multi-leaf progressive spring rate design that provides a smooth ride under any load while maintaining factory payload weight ratings.

Important Notes

The 1/2 ton commonly came with a factory 52-inch eye-to-eye rear leaf spring. However, some were produced with a 56-inch rear spring. If ordering rear leaf springs, be sure to 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. #001408 comes with OE style rubber bushings installed. Exhaust modification may be required to clear the front driveshaft.
