Jeep Wrangler JK 2007-2018, TeraFlex Alpine IR Short Arm Pair, 2-4in Lift

Short factory arms bind as the suspension cycles, and on a lifted JK that bind shows up as a stiff ride and worn bushings. Rock crawling makes it worse.

TeraFlex Alpine IR short arms are adjustable for 2-4 in of lift and use maintenance-free Independent Rotation bushings that allow unrestricted rotation and flex, with good NVH damping to improve on-road and off-road ride quality. They bolt to the factory control arm mounts and can be added to any existing lift. Pick the arm position you need and the geometry is dialed in.
