4 Inch Lift Kit | RR Spring | Chevy/GMC C10/K10 C15/K15 Truck/Half-Ton Suburban (69-72)

Transform the stance and capability of your GM classic with Rough Country’s 4" Suspension Lift Kit, designed specifically for Chevy/GMC C10/K10, C15/K15 Truck/Half-Ton Suburban models from 1969 to 1972. This bolt-on system delivers a leveled, aggressive look while boosting ground clearance and off-road readiness, all without the hassle of complex modifications.

Ride quality that meets rugged ambition

Engineered for a superior ride, the kit uses application-specific front and rear lifted leaf springs to preserve precise handling and comfort. By eliminating rear lift blocks, you gain consistent lift and improved suspension geometry, resulting in a smoother, more controlled feel—closer to a factory ride even with the added height. Brake line brackets are included to maintain proper alignment and safe suspension travel throughout every mile and obstacle.

Performance you can feel

Rough Country pairs this lift with the N3 Series shocks, tuned right for your exact application. Expect a dependable balance of highway civility and off-road confidence thanks to:

• 10-stage variable valving for precise damping across terrain
• High-pressure nitrogen charge for repeatable performance
• 54mm shock body and 18mm piston rod for durability and strength

Genuine off-road capability with room to grow

Crave a bolder look without sacrificing daily drivable comfort? This 4" lift creates ample clearance for larger wheel-and-tire combos, enabling up to 35" tall tires with proper backspace. The result is a more imposing stance, improved approach and departure angles, and expanded off-road capability—perfect for weekend adventures or tackling rough backroads.

Built to last, backed by Rough Country

Like all Rough Country products, this kit is built for longevity and confidence on and off the road. It’s covered by a Limited Lifetime Warranty, so you can enjoy the upgrade today and rely on it tomorrow.
