This lift kit is built around replacement upper control arms that dwarf factory components and are made from fully-welded 1/8 steel plate and CNC-machined ball joint and bushing mounts to provide significant gains in suspension travel. The arms utilize high quality ball joints that can handle heavy-duty use and work in conjunction with stock-style rubber mount bushings to provide a quiet ride. A fully integrated front differential drop and differential skid plate system relocates the differential for optimal driveline angles. The included strut spacers provide a full 3.5 of lift and install easily on the factory struts without requiring the use of a strut compressor. A block and U-bolt system nets 2 of lift and provides an athletic level vehicle stance.
