Supension Lift Kit

The Rough Country Suspension Lift Kit (Model 250) delivers a proven 4-inch lift for full-size GM trucks and SUVs from 1973 through 1991, making it an essential upgrade for owners seeking improved ground clearance, off-road capability, and a more aggressive stance. This kit addresses the factory suspension limitations of classic and vintage GM vehicles, providing the foundation needed for larger tires, better approach angles, and enhanced payload capacity. Whether you're restoring a classic C10 Chevy or building a capable off-road platform, the RCS250 lift kit is engineered to meet the demands of serious enthusiasts who refuse to compromise on quality or performance.

Built with a comprehensive component architecture, this suspension lift kit includes heavy-duty leaf springs, reinforced u-bolts, polyurethane bushings, and precision-machined steering arm components—all engineered to maintain factory ride geometry while extending the suspension travel envelope. The leaf spring design preserves the original suspension characteristics of these vehicles while the upgraded bushings eliminate play and improve articulation for both street and trail use. At 249 pounds, the complete kit is substantial enough to indicate quality construction; the integrated steering arm geometry prevents the common pitfall of bump steer that plagues improperly engineered lift systems. Hardware is grade-rated for the structural loads imposed by lifted platforms, ensuring longevity and reliability over tens of thousands of miles.

This kit is ideal for owners of 1973–1991 GM full-size trucks and SUVs—including Chevrolet and GMC models—who demand authentic engineering backed by proven track records in both street and off-road environments. Professional installation is strongly recommended; proper wheel alignment and steering geometry checks are essential to maximize suspension performance and tire life after installation. The RCS250 pairs seamlessly with larger tire packages and aftermarket wheels, opening possibilities for custom builds while maintaining the structural integrity and handling characteristics that experienced mechanics demand from lift systems.
