TeraFlex JL: Alpine IR Long Control Arms Kit – Front Lower (3-6” Lift)

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.

On higher lifts, Alpine IR Long Control Arms and Brackets (NOT INCLUDED) reposition the frame-end control arm mounting points to restore near factory orientation to reduce bushing stress during droop and shock load transferred through the control arms. Can be added to an existing suspension lift.

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