Description
TeraFlex JK: Alpine IR Long Arms and Long Arm Brackets provide complete alignment adjustability and dependability for maximum performance on JK Wrangler/Unlimited models with 3-6 Inch Lifts.
Our innovative, maintenance-free IR Bushings provide unrestricted rotation and flex as well as excellent NVH damping to improve on- and off-road ride quality and performance. CAD-engineered TeraFlex JK: Long Arm Brackets are designed 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. Can be added to any existing suspension lift.
