TeraFlex Alpine Upper Control Arms are a major upgrade for the 2021+ Ford Bronco platform. Built from cast 6061 Aluminum, these UCAs are strong, lightweight, and engineered for hard trail use. When paired with Falcon 3.3 Coilovers, the Bronco gains additional travel, improved ride quality, and noticeably better control on and off the road. 

On the steering knuckle side, our fully adjustable for wear Heavy-Duty Ball Joint provides simple preload adjustment as wear develops—no costly rebuilds or downtime. On the frame side, our IR bushings deliver maintenance-free comfort, smoother rotation, and more articulation than the factory arms—maximizing the performance potential of Falcon shocks. 

If you want your Bronco to handle the trail like a monster and still drive amazing on the street, this is the arm set that unlocks it.
