Pair of TeraFlex Rear Upper Adjustable Alpine IR Flexarms for 2020-2021 Jeep Gladiators with a 0-4-1/2" Lift.

Free your restricted suspension with pair of TeraFlex Rear Upper Adjustable Alpine IR Flexarms 1417580 for your 2020-2021 Jeep Gladiator's driver and passenger sides. Designed for an existing 0-4-1/2" lift, the Flexarms offer independent rotation bushings for a full flex and articulation during serious off-roading. And while you flex on rough terrain your flexarms and bushings will dampen normal lifted vehicle noise, harshness and vibration for a smoother, quieter ride.

Teraflex's Alpine IR Control Arms provide complete alignment adjustability and re-center axles in the wheel well while increasing the wheelbase. The optimized caster angle and tuned anti-squat geometry ensure proper suspension alignment that is finely secured with forged threaded joints and anodized clamp collars to secure rod ends.
