Factory Feel with Showroom Stance
Designed to maintain the factory track width, Zone’s HD kit delivers a confident ride that corners like stock while offering extra ground clearance for 35" tires. Stainless steel braided brake lines, CNC-machined ductile iron knuckles, and a 3" rear lift block round out the performance package. Fox 2.0 IFP steel-body shocks come standard to ensure premium comfort and control both on and off-road.
No Drilling. No Differential Cutting.
Zone engineered this suspension system for ease of installation—no trimming the differential housing required. The front differential parts are simply not used in 2WD models, ensuring every install is as clean and non-invasive as possible. Shock boot covers also come included to guard against rock damage during aggressive off-road use.
