      Description

      Advanced Suspension Upgrade. The Rough Country 3.5-Inch Knuckle Suspension Lift Kit with Premium N3 Shocks enhances the Silverado 2500 HD by increasing ground clearance and improving ride quality. This upgrade boosts off-road capability while maintaining smooth on-road handling and control.

      Construction and Appearance. Made from precision-engineered steel with forged components, this lift kit prioritizes strength and durability. Forged upper control arms use OEM-style Clevite bushings for smooth operation, while steel knuckles and torsion bar keys provide robust support. Control arms are available in aluminum or powdercoated finishes for a rugged yet refined look.

      Installation. The bolt-on design requires no cutting, drilling, or welding, making installation straightforward. The process typically takes 4 to 6 hours with standard tools. For ease of installation, the use of a torsion bar removal tool is recommended.

      Warranty. This suspension lift kit comes with a limited lifetime replacement warranty, ensuring long-term reliability and peace of mind.

      Application. Designed to fit 2011–2019 Silverado 2500 HD models equipped with factory overload springs and without MagneRide suspension. Not compatible with dually models due to U-bolt design differences.
