TeraFlex JK: Alpine IR Long Control Arms and Alpine Long Arm Brackets (NOT INCLUDED) provide complete alignment adjustability for maximum performance on JK Wrangler/Unlimited models with 3-6" lifts. Can be added to an 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 Long Arm Brackets 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.
Must be used with Alpine Long Arm Bracket Kit (# 1957000) - NOT INCLUDED. Our CAD-designed TeraFlex JK: Alpine Long Arm Brackets are engineered for maximum strength. By streamlining the frame-end mounting points, we were able to incorporate both upper and lower mounts in each bracket thus simplifying installation while maintaining a factory appearance.
