20202021 GM 2500 / 3500 HD 3IN ADVENTURE SERIES (OE KEY 84634344) W/ OVERLOADS

High strength UCAs are boxed and fully welded. They are specially designed with an indexed ball joint cup to correct ball joint operating angle for more suspension travel. Cast construction indexed torsion bar keys to provide additional ride height while maximizing ground clearance. Front differential relocation brackets to correct CV axle operating angle. Sway bar relocation brackets to maintain clearance and proper operating angle. 2\" rear lift blocks and heavy duty u-bolts to level the stance. Maintains ride and handling characteristics with clearance for 35\" tires. Allows for improved offroad performance with more droop travel. Engineered for easy bolt on fitment and improved travel, these 3” Adventure Series Lift Kits bridge that gap between an entry level leveling kit and full IFS lift system offering next level performance without the cost and extensive installation. The heart of this new system is a pair of heavy duty replacement upper control arms (UCAs) designed to improve range of motion for more suspension travel when wheeling in rough terrain. These new control arms dwarf the factory units and are built from high strength steel, boxed and fully welded with CNC-machined bushing and ball joint cups repositioned to operate in the neutral position at 3” of lift. They use OE durometer rubber bushings and greaseable OE-style heavy duty ball joints for quiet, reliable operation and superior corrosion resistance to uniball style control arms. Along with the arms, a pair of reindexed cast steel torsion bar keys are supplied up front to lift vehicle. Zone Offroad includes a small differential relocation kit (4WD models only) to correct CV axle operating angles without effecting ground clearance. The sway bar operating angle is corrected with the use of a pair of relocation brackets allowing for full droop of the suspension and proper clearance. In the rear a 2” block and u-bolt kit is used to create a level to slightly tail high stance.
