Teraflex Alpine IR Long Arm & Bracket Kit - 3in-6in |1310510

Daily drivers and die-hard Jeepers can reap the rewards from the JL Alpine IR Long Arm and Bracket Kit

TeraFlex JL 4dr: Alpine IR Long Control Arms & Alpine Long Arm Brackets provide complete alignment adjustability for maximum performance on JL Wrangler/Unlimited models with 3-6” lifts. Suspension drooping, flexing, axel torque, and just daily road use can put major stress on your bushings. TeraFlex has curated IR (Independent Rotation) bushings essentially eliminate common bushings and joint failure. The IR Bushings provide unrestricted rotation and flex as well as excellent NVH damping and ride quality. A 2-piece, hard steel bearing surface rotates inside the bushing as the suspension droops and compresses. 2 O-rings protect the inside from any debris and keep the bushings truly maintenance-free. On higher lifts, Alpine IR Long Control Arms and Brackets reposition the frame-end control arm mounting points to restore near factory orientation. TeraFlex has streamlined frame-end mounting points provide both upper and lower mounts in each bracket, keeping installation simpler and maintaining a factory look.

 

Innovative Independent Rotation bushings are built to last for extreme off-road use

Alpine Long Arm Brackets reposition the frame-end control arm mounting point. This aims to restore near factory orientation, reducing bushing stress during droop and shock load transferred through the control arms. Premium black e-dipped coating provides superior durability and corrosion resistance on tube and forged rod end housing. This package can re-center axles in the wheel well for proper suspension movement and can also be used to increase wheelbase. Adjustable Alpine IR Long Control Arms optimize caster angle and tune anti-squat geometry for proper suspension alignment. Can be added to an existing suspension lift. 

 

Alignment and removal of factory control arm bracketry is required.
