Whiteline 2021+ Ford Bronco Front Upper Control Arm

Correct Bump Steer And Camber Loss From Lifted Suspension

Raising a Bronco with a lift kit or larger tires pushes the factory upper control arm geometry out of its designed range, which can introduce bump steer, uneven camber, and accelerated ball joint wear. This Whiteline KTA312 front upper control arm is engineered with corrected geometry to restore proper alignment range after a lift, keeping the front suspension tracking true and reducing uneven tire wear.
