Description

The Rough Country 7.5" Suspension Lift Kit, designed for 2011-2019 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks, aims to enhance their aggressive stance and style while preserving factory functionality. Its Non-Torsion Drop (NTD) design improves ground clearance and handling without altering the truck's factory angles or axle placement, utilizing robust 1/4" thick steel crossmembers, 1/2" NTD brackets, and a durable Hammer Black skid plate. It also maintains factory axle positioning to prevent premature wear and requires no modifications to the drivetrain or exhaust system. Buyers can further customize their ride by selecting from various shock options, including N3, M1, V2 monotubes, or premium Vertex reservoir shocks. This lift kit offers significant ground clearance for tackling tough terrain. It fits 2011-2019 GMC Sierra 3500 HD (4WD/2WD), Chevy Silverado 2500 HD (2WD/4WD), GMC Sierra 2500 HD (2WD/4WD), and Chevy Silverado 3500 HD (2WD/4WD) models. **Important Notes:** This kit requires minor cutting and drilling for installation. It does NOT fit dually models due to u-bolt design variations. Gas models may require exhaust modification for driveshaft clearance. Models with factory rear overload springs will need a longer u-bolt kit (SKU: 7664). A torsion bar removal tool (SKU: 1067) is recommended for easier installation. This kit does NOT work with factory wheels; models with factory 17-inch wheels must use 17-inch or larger aftermarket wheels due to larger brake calipers and rotors.
