Overview
If you're looking to give your Chevrolet Silverado 1500 or GMC Sierra 1500 a more aggressive stance and improved off-road capability, this 6" lift kit from Zone Offroad is a great place to start. This system includes everything needed for a complete installation, from high-strength crossmembers and steering knuckles to differential relocation brackets designed to maintain proper driveline angles. To suit different build preferences, the kit offers multiple front suspension options. The first option utilizes OE strut spacers that retain the factory front struts and can be paired with either FOX 2.0 Adventure Series rear shocks for enhanced performance or Zone Nitro twin-tube rear shocks for a dependable ride at a great value. The second option features bolt-in ready Zone Nitro loaded struts that come preassembled for quick installation and are paired with Zone Nitro rear shocks for a matched suspension setup. Engineered for strength, performance, and reliability, this lift kit delivers the aggressive stance and off-road capability you’re after while providing clearance for tires up to 35 inches.
