Introducing the GMC K15 Suburban Suspension Lift Kit - Front + Rear - Rough Country - 6 Inch + N3 Series Shocks for models '77-'78. This comprehensive lift kit transforms your GM truck’s stance and enhances its capability, offering a leveled, aggressive look while bolstering ride height and off-road performance.

This Rough Country lift kit is meticulously engineered to deliver a superior ride quality. It includes application-specific front lifted leaf springs that increase ground clearance without compromising comfort or control. The rear lift utilizes blocks, add-a-leafs, and brake line brackets to maintain proper geometry, ensuring a smooth, factory-like ride after installation. For those seeking a complete suspension overhaul, optional replacement rear lifted leaf springs are available, providing a consistent rear lift and negating the need for lift blocks.

Enhance your driving experience further with the N3 Series Shocks included in this kit. These shocks are perfectly valved for your specific application, striking an ideal balance between on-road smoothness and off-road capability. They feature a 10-stage variable valving system, a high-pressure nitrogen charge, and a robust 54mm shock body with an 18mm piston rod, ensuring performance and durability.

This lift offers ample clearance for aggressive wheel and tire combinations, allowing you to fit up to 37-inch tall tires with proper backspacing. Additionally, a raised steering arm is included to correct the steering geometry, ensuring tight, responsive handling post-lift.
