Take your new HD to the next level with the 3" Adventure Series Lift Kit from Zone Offroad. 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 strnegth 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. Rounding out the kit are a set of Nitro gas or FOX adventure series IFP gas shocks at all 4 corners for a smooth ride and impressive performance across any terrain. Take your late model GM 2500HD to the next level with Zone Offroad!
