The GMC Sierra 3500 HD Suspension Lift Kit by Rough Country offers a comprehensive lifting solution designed for model years '11-'19. With this kit, you achieve a 3.5-inch lift that enhances your vehicle's ground clearance and optimizes your ride quality whether you're cruising the highways or tackling rugged terrains.

Built with innovative design and robust materials, this suspension lift kit combines durable steel knuckles with forged upper control arms to effectively reduce CV angles. The inclusion of forged torsion bar keys ensures that strength and rigidity are not compromised, allowing for a significant lift in elevation. The robust construction not only enables clearance for 33-inch tires with appropriate wheel backspacing, but also retains the factory-like geometry, significantly improving the driving experience. Rough Country's suite of shocks, including the optional N3 series, V2 Monotube, and Vertex adjustable coil-overs, provides various suspension solutions to suit your specific needs, whether for everyday use or elevated adventures.
