Description

Transform your GM truck with Rough Country's 6-Inch Suspension Lift kit, engineered for the 2021-2024 GMC Sierra 1500 and 2021-2024 Chevy Silverado 1500. This system delivers a 6-inch lift, providing enhanced ground clearance for improved off-road capability and a bold aesthetic. The kit features a high-clearance crossmember design that maintains optimized suspension geometry for proper alignment and superior handling, ensuring off-road performance without sacrificing ride quality. It retains the factory track width, allowing for the fitment of up to 35x12.50 tires on 10-inch wide wheels with 4.5-inch backspacing. For extreme durability, it includes heavy-duty cast knuckles and fabricated blocks that outperform traditional cast blocks. The precision-engineered, laser-cut materials are crafted with advanced computer-aided design for a perfect fit and reliable performance. Installation requires cutting and drilling. It does not fit factory wheels; 20-inch or larger aftermarket wheels with 4.5-inch backspacing are required. Test fitting wheels prior to installation is recommended, and some aftermarket wheels may require a 0.25-inch wheel spacer (#1065).
