The Zone Offroad ZONC37 is a 3-inch Adventure Series Lift Kit designed for 2011-2019 GM Silverado/Sierra 2500HD/3500HD models without overload springs. It features adventure series fully boxed HD upper control arms for improved strength and suspension travel, offering improved ride quality and suspension travel over standard "leveling kits". A front differential drop is included to correct CV shaft angles, and a rear 2" rear block kit will net a level to slightly tail high stance. Indexed torsion bar keys are included to set ride height, allowing clearance for up to 35" tires. This kit provides everything needed from high strength upper control arms and indexed torsion bar keys to differential relocation spacers and a rear lift block kit to complete the installation.
