  • TeraFlex Alpine IR Adjustable Rear Upper Control Arms deliver increased strength, improved travel, and precise axle control for the 2021+ Ford Bronco. Designed for lifted Broncos, these adjustable UCAs allow accurate pinion angle and axle alignment adjustment to maximize driveline life, traction, and suspension performance. 

    Our Independent Rotation (IR) Bushings eliminate bushing bind and reduce NVH, allowing smoother suspension cycling and increased articulation off-road while maintaining a calm, controlled ride on pavement. These arms are built strong for serious trail use and pair perfectly with Falcon shock systems for further suspension gains and down travel potential. 

    When used together with the matching Alpine IR Adjustable Rear Lower Control Arms, the Bronco rear suspension becomes dramatically more stable, predictable, and tuned for real-world off-road use without giving up on-road comfort.
