This variant uses a front strut spacer for 3.5" of front lift paired with FOX Adventure Series rear shocks and a 2" cast lift block for 2" of rear lift. The FOX Adventure Series shocks feature a nitrogen-charged twin-tube design with 10-stage velocity-sensitive valving, dual-welded ends, self-lubricating seals, a 2-inch diameter steel body with black powder coat finish, and application-specific valving for maximized performance.
Overview
The Zone Offroad 3.5" Adventure Series lift kit goes beyond a standard leveling kit by incorporating Adventure Series upper control arms (UCAs) for improved off-road performance and increased suspension travel, with clearance for up to 35" tires. Front lift is achieved through a 2-piece combination top-mount and preload strut spacer design that delivers a full 3.5" of lift without overextending the suspension at full droop. Optional weld-in steering stops are included to support up to 35" tire fitment. The rear is lifted and leveled with a cast 2" lift block.
