Elevate Your Stance. Maintain Your Ride: Rough Country's 6" NTD Suspension Lift Kit for 1999-2006 Chevy/GMC 1500 pickups delivers aggressive lift performance without compromising comfort or drivability. This high-clearance kit offers unmatched ground clearance for tackling tough terrain and clears 35" tires with ease. Thanks to its factory torsion bar placement, the kit maintains OEM alignment and geometry preserving your truck's factory ride and handling feel while eliminating the nose-down stance.

Built for Strength. Engineered for Precision: Designed with innovation in mind, this kit includes heavy-duty steel knuckles, precision-engineered differential brackets, and OEM axle geometry retention to minimize wear on critical components. The upgraded fabricated lift blocks are stronger than cast blocks and feature an anti-axle wrap design, improving rear stability under load or acceleration. Plus, factory travel stops are reused, ensuring consistent suspension performance on and off the road.

No Compromises. All Performance: The kit's non-torsion bar drop brackets keep the torsion bars tucked high and protected, while the Autotrac-compatible design ensures seamless fitment for 4WD models with electronic transfer cases. It's a 100% bolt-on system no cutting, no drivetrain changes, no exhaust relocation required for a clean install with long-term reliability. Choose your ride quality with configurable shock options, including our nitrogen-charged N3, V2 Monotube, or M1 Monotube shocks for tailored performance.

Installation Made Simple: With simplified installation and redesigned components, this kit cuts down the install time and complexity. Basic cutting and drilling are minimal, and installation can be completed in 8-10 hours with standard tools. Whether in your garage or by a professional, getting your truck lifted has never been easier.

Peace of Mind Included: Rough Country backs this lift kit with our Limited Lifetime Replacement Warranty, protecting against defects in materials and workmanship. Trust in our rugged engineering and enjoy the road ahead with confidence.
