Jeep Wrangler JK 4-Door 2007-2018, TeraFlex 4in Alpine RT4 Long Arm Suspension System, No Shocks

Trails, rocks and highway miles all load the same suspension. A 4 in lift with the wrong geometry gives you one of those and costs you the other two.

The TeraFlex Alpine RT4 pairs Alpine IR long control arms and brackets with front and rear HD forged adjustable track bars for full suspension adjustability. The arms balance front caster and pinion angles and optimize rear pinion angle, anti-squat geometry and tire position at 3-6 in of lift. The Independent Rotation bushings remove bushing bind through full travel, and the brackets move the frame-end mounts back toward the factory orientation to reduce bushing stress during extreme droop.

SpeedBump stops, sway bar disconnects, braided brake lines and an exhaust spacer kit come with the system. Add shocks, align the axles and head out.
