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

Raise the stance and unleash the capability of your 1969–1972 GM pickup or Suburban with Rough Country’s 4-Inch Suspension Lift Kit. Designed specifically for Chevy/GMC C10/K10 and C15/K15 truck/hard-to-define Suburban platforms, this bolt-on kit delivers a balanced, aggressive look and real off-road performance without compromising daily drivability.

What makes this kit different

• Application-specific front lifted leaf springs replace the factory setup to gain true 4 inches of lift while maintaining a comfortable, predictable ride quality. The springs are tuned for your exact model to optimize load handling and on-road feel.
• Rear lift blocks and brake line brackets preserve geometry and alignment, ensuring steering, braking, and suspension performance feel as solid as stock once you’re back on the road.
• N3 Series shocks come standard and are engineered for your exact application. With a 10-stage variable valving, a 54mm shock body, and an 18mm piston rod, they strike a precise balance between highway smoothness and off-road control, plus a high-pressure nitrogen charge for consistent performance under load.
• Up to 35" tire clearance—this 4" lift creates ample room for robust wheel-and-tire combos with proper backspacing, letting you conquer trails with a commanding, rugged look.
• Limited Lifetime Warranty provides long-term confidence that this kit is built to endure the trails and the daily commute.

Ride, handling, and real-world use

Despite the elevated stance, the kit is engineered to preserve a factory-like ride quality. The combination of front lifted leaf springs and tuned N3 shocks delivers composed on-road manners, reduced squat during acceleration, and controlled damping over rough pavement. Off the pavement, the enhanced ground clearance and improved approach angles help you tackle rocky trails, rutted dirt, or snow-packed grades with confidence.

Who it’s for and ideal use cases

This lift kit is ideal for classic GM trucks and Suburbans owners who crave a bold, lifted silhouette without sacrificing daily comfort. It’s perfect for weekend off-road excursions, hunting or camping trips where clearance matters, or simply for enthusiasts who want a tougher, more capable truck-on-street presence. If you’re aiming to run larger tires (up to 35"), this kit provides the room to do so while maintaining predictable handling.

Compatibility, installation, and care

Engineered for the Chevy/GMC C10/K10 C15/K15 Truck/Half-Ton Suburban 1969–1972 range, the kit is designed for straightforward bolt-on installation. Expect a direct upgrade path that preserves geometry and ride quality, followed by a professional alignment to maximize tire wear and steering precision. After installation, routine checks of bolts, bushings, and shock mounts will help sustain performance and longevity.

Why choose this kit over others

What sets this 4-Inch Lift Kit apart is the thoughtful combination of lifted front leaf springs, geometry-preserving rear blocks and brake line brackets, and N3 shock technology tuned for your specific model. The result is an aggressive, capable stance without an unpredictable ride, plus the confidence of a Limited Lifetime Warranty that stands behind performance mile after mile.
