Description

The Rough Country 6-inch Suspension Lift Kit is engineered to enhance the capability of your 1977-1991 GMC Suburban 3/4 ton 4WD vehicle. This comprehensive kit includes front lifted leaf springs, a steering arm, brake line relocation brackets, U-bolts, and all necessary hardware for the front installation. The rear of the vehicle benefits from lifted leaf springs, 2-inch lift blocks, U-bolts, and hardware. The kit is equipped with four premium N2.0 series shock absorbers, designed to offer a balanced performance suitable for both on-road and off-road driving conditions. Important notes for installation specify that this kit is ONLY compatible with models featuring front and rear solid axles and ONLY with factory rear leaf springs measuring 56 inches. If your vehicle is equipped with a front sway-bar, drop brackets (SKU: 1019) are recommended. Additionally, if your GMC Suburban has factory front quad shocks (four total front shocks), a Factory Quad Shock kit (SKU: Q20027) must be added. This lift kit is designed for the 1977-1991 GMC Suburban 3/4 ton models with 4WD and 56-inch rear leaf springs. Installation is estimated to take between 6-8 hours.
