Quick Overview
Zone Offroad provides a great way to bridge the gap between a leveling kit and a full size suspension lift kit that’s cost effective and much simpler to install. Featured in this lift kit is a set of heavy duty replacement upper control arms that improve the range of motion for more suspension travel over rough terrain. These control arms dwarf factory control arms and are constructed using high strength steel, boxed and fully welded with CNC machined bushings and ball joint cups that are repositioned to operate in the neutral position at 3” of lift. Included are OE durometer rubber bushings and greasable OE-style heavy duty ball joints that ensure a quiet and reliable operation with superior corrosion resistance to uniball style arms.
Reindexed cast steel torsion keys lift the front of the vehicle. The CV axle operating angle is corrected with a small differential relocation kit. This will not affect ground clearance. Sway bar relocation brackets allow for full droop of the suspension. The rear lift is a 2” block and u-bolt kit that creates a level to slightly tail high stance. A set of FOX Adventure Series IFP gas shocks complete this package. Included in the Zone Offroad lift kit for your Silverado or Sierra 2500HD or 3500HD are the following:
