Jeep Wrangler JL 2-Door 2018-2026, TeraFlex Alpine RT4 4.5in Long Arm Suspension System, No Shocks

A 4.5 inch lift is a big change in geometry, and the factory arms, mounts and bushings were not made for it. The TeraFlex Alpine RT4 long arm system covers the highway, the desert and the rocks with bolt-on Alpine IR long control arms and brackets, HD forged adjustable track bars and track bar brackets that allow full adjustment. Independent Rotation bushings remove bushing bind through full travel, the long arm brackets restore near-factory mounting orientation to reduce bushing stress on higher lifts, and SpeedBump bump stops smooth out unexpected hits.

Install the springs, arms, brackets, track bars and bump stops, set the alignment, and add Falcon shocks. The Jeep rides quietly and flexes freely.

• Alpine IR long control arms and brackets with Independent Rotation (IR) bushings remove bushing bind during full suspension travel
