Description

The Rough Country 7-Inch Suspension Lift Kit is engineered to give your 2014-2016 GMC Sierra 1500 or Chevy Silverado 1500 4WD an aggressive stance and towering ride height. This kit maintains the factory track width, ensuring tight and predictable handling, and is compatible with OEM 20-inch wheels, allowing the use of up to 35-inch tires without aftermarket spacers. Built with durability in mind, this complete system features laser-cut front and rear crossmembers, front and rear skid plates, and loaded strut assemblies crafted by Rough Country's R&D team. Out back, high-strength fabricated 6-inch lift blocks with an anti-axle wrap design are included to maintain stock ride quality while preventing axle wrap. The kit comes standard with Nitrogen-charged N3 Shocks, featuring 10-stage velocity-sensitive valving, and is fully compatible with other Rough Country shock and strut upgrades, including the Vertex reservoir series. Installation requires cutting and drilling. This lift kit does NOT fit models with stamped steel control arms; verify if your stock control arms are cast aluminum, cast steel, or stamped steel for proper fitment. It also does NOT fit Denali models equipped with Magnetic Ride Control or models with the eAssist (ECO Hybrid) package. For models with a mass damper on the front differential, it must be removed to ensure adequate clearance when lowering the differential. Installation of larger tires will require Rough Country's Speedometer Calibrator SKU: 90009.
