TeraFlex JK: Alpine IR Long Control Arms and Alpine Long Arm Brackets provide complete alignment adjustability and dependability for maximum performance on JK Wrangler/Unlimited models with 3-6 Inch 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 TeraFlex JK: Alpine Long Arm Brackets (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.
CAD-engineered Alpine 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.
