TeraFlex JL 2 Door Alpine IR Long Control Arms and Alpine Long Arm Brackets provide complete alignment adjustability for maximum performance on JL Wrangler/Unlimited models with 3-6 inch lifts. Includes our innovative IR (Independent Rotation) Bushings.

On higher lifts, Alpine IR Long Control Arms and 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. Can be added to an existing suspension lift.

These CAD-designed TeraFlex JL 2 Door 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.
