Transform your GMC truck's stance and capability with the GMC K15 Suspension Lift Kit by Rough Country. Designed specifically for 1977-1978 models, this 6-inch lift kit featuring 52" rear leaf springs not only elevates your truck's ride height but also enhances its off-road performance with a simple and reliable bolt-on installation process.

The Rough Country 6" Suspension Lift Kit offers superior ride quality thanks to its application-specific front lifted leaf springs. These springs deliver increased ground clearance without compromising ride comfort or control. The inclusion of rear lift blocks, add-a-leafs, and brake line brackets ensures that your vehicle maintains proper geometry, resulting in a smooth drive akin to a factory-like experience post-installation. Additionally, the kit can be upgraded with replacement rear lifted leaf springs for consistent rear lift, eliminating the need for lift blocks entirely.

Enhancing your off-road adventure, the kit comes standard with Rough Country's N3 series shocks, precisely valved for your specific application. These shocks are engineered with a 10-stage variable valving system, high-pressure nitrogen charge, and a robust 54mm shock body with an 18mm piston rod, ensuring a perfect balance of on-road and off-road capabilities. This durable design guarantees long-lasting performance.
