TeraFlex JL: Alpine IR Long Control Arms and Alpine Long Arm Brackets (NOT INCLUDED) provide complete alignment adjustability and dependability for maximum performance on JL Wrangler/Unlimited models with 3–6” lifts. Can be added to any existing suspension lift.

Our innovative IR Bushings provide unrestricted rotation and flex as well as excellent NVH damping. These maintenance-free bushings improve on- and off-road ride quality and performance.

Must be used with Alpine Long Arm Bracket Kit (JL 2-Door: 1958002 or JL 4-Door: # 1958000) – NOT INCLUDED.
