Introducing the GMC K15 Suburban Suspension Lift Kit by Rough Country, designed specifically for models from 1977 to 1978. This 6-inch lift kit includes 52" rear leaf springs and is engineered to enhance your vehicle's stance and performance, providing both aesthetic appeal and rugged off-road capability.

This premium lift kit is an excellent choice for those looking to upgrade their GM truck from front to back. With its easy bolt-on installation, it not only delivers a leveled, aggressive look but also significantly enhances ride height and off-road readiness. Designed to maintain superior ride quality, the kit includes application-specific front lifted leaf springs. These springs increase ground clearance without sacrificing ride comfort or control. To ensure a smooth, factory-like ride post-installation, it features rear lift blocks, add-a-leafs, and brake line brackets.
