Zone Offroad is now offering the first of several new lift and leveling kit options for the redesigned 2020 Chevy Silverado 2500HD/3500HD and GMC Sierra/Denali 2500HD/3500HD trucks with new 2" leveling kits. While the suspension on the new 2020 trucks has some similarities to the previous models, there are several minor changes that required a new leveling kit to allow for optimal performance. At the heart of this 2" leveling kit are a pair of nodular cast iron torsion bar keys for strength and feature indexed torsion bar slots designed to properly lift/level the stance. Also supplied are a pair of torsion bar bolt keepers to prevent the bolt from slipping off the key during extreme off-road use. This kit allows the use of factory shocks with the supplied upper shocks extensions and is designed to offer more suspension travel without worry of overextending at full droop. This kit is easy to install using a torsion bar tool and can be completed in 1-2 hours. The final result is a leveled stance, comfortable ride and handling and clearance for up to 35" tires.
