A lifted JK that still runs stock-length rear control arms runs out of adjustment quickly. The axle drifts out of position, the bushings bind at full droop, and every trip carries the worry that the suspension is fighting the lift. The TeraFlex Alpine IR rear long arm kit gives the rear axle adjustable long control arms with IR bushings that rotate without restriction and damp noise and vibration, with no maintenance. The included Alpine Long Arm Brackets move the frame-end mounting points back toward factory orientation, which reduces bushing stress during droop and shock loads. Install the brackets and arms, set alignment, and the rear axle stays put.
