This is a standard front-half kit — it includes the crossmember, upper and lower adjustable control arms, and all hardware. The longer arm geometry reduces front suspension angles at lift height compared to short arm geometry, resulting in a smoother on-road ride, greater off-road articulation, and reduced wear on related components. The frame-end joints are Currie Johnny Joints — 40° of unrestricted movement with Tough 88 urethane casing for shock absorption and NVH isolation. The axle-end joints are GIIRO dual-durometer bushings — maintenance-free, self-centering, and NVH-isolating. No welding required. For the Pro Series 3-link front upgrade kit with weld-on brackets, a 3-piece crossmember, and a single upper 3-link arm for maximum articulation, see COR-4804341.
