Description

The Rough Country 6" Basic Lift Kit is engineered to enhance the off-road capability of your truck, Jeep, or SUV. This kit provides increased ground clearance, allowing for the fitment of larger tires and wheels, and improves your vehicle's ability to negotiate tough terrain. It includes essential components such as front knuckles, front and rear crossmembers, front upper strut spacers, front differential drop brackets with a skid plate, front sway bar drop brackets, rear fabricated blocks, and rear brake line brackets. The kit retains the factory track width for a stable ride and allows for 35x12.50 tires on 10-inch wide wheels with 4.5-inch backspacing. Durability is a key feature, with heavy-duty cast knuckles and superior fabricated rear blocks. Installation requires cutting and drilling. While some kits can be installed at home, professional installation and a post-lift alignment are strongly recommended. This specific kit is designed for 2021-2024 Chevy Silverado 1500 (2WD/4WD) and 2020-2024 GMC Sierra 1500 (2WD/4WD). It is crucial to note that this kit ONLY fits GMC Denali or Denali Ultimate models equipped with Adaptive Ride Control and Chevy High Country models equipped with Adaptive Ride Control. It does NOT fit factory wheels, and 20-inch or larger aftermarket wheels with 4.5 inches of backspacing are required. Some aftermarket wheels may also require a 0.25-inch wheel spacer.
