77-91 GM P/U 3500 6in Suspension Lift Kit

The 77-91 GM P/U 3500 6-inch suspension lift kit from Rough Country is designed for full-size Chevrolet and GMC 3500 pickup owners seeking significant ground clearance and a commanding stance without compromising drivability. This lift system addresses a common modification goal: raising your truck's ride height to accommodate larger tires, improve approach and departure angles, and enhance overall visual presence while maintaining structural integrity.

Rough Country's design uses a proven coil spring lift architecture that works in concert with your truck's existing suspension geometry to maintain proper wheel alignment and handling characteristics. The 6-inch height gain is achieved through precision-engineered coil springs that replace OEM units, allowing the suspension to extend further while keeping the chassis level and reducing body roll during cornering. This approach avoids the complications of body lifts and maintains the integrity of brake lines, fuel delivery systems, and electrical harnesses—critical factors often overlooked in amateur installations.

Whether you're preparing for off-road adventures, overlanding, or simply want a more aggressive profile, this kit delivers the suspension geometry changes necessary for a smooth 6-inch elevation. The kit's substantial weight reflects the heavy-duty construction and multiple precision components required for a safe, long-term suspension modification on trucks carrying substantial payloads. This suspension lift kit is compatible with 1977–1991 Chevrolet C/K Series and GMC Full-Size Pickup models.
