TeraFlex 8 Arm 3-6" Lift Alpine IR Long Control Arm Kit; Jeep Wrangler JK & JK Unlimited

The TeraFlex JK Alpine IR Control Arm Kit provides complete alignment adjustability for maximum performance on JK & JKU Wrangler models with 2-4" lifts. Includes the innovative Independent Rotation Bushings, can be added to any existing suspension lift!

Must be used with Alpine Long Arm Bracket Kit (# 1957000) – NOT INCLUDED. The 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.

On higher lifts, Alpine Long Arm Brackets will reposition the frame-end control arm mounting points to restore almost factory orientation to reduce bushing stress during droop and shock load transferred through the control arms.
