About this part

Forged Upper Control Arms, fitment-checked

Forged aluminum upper control arms for the 2021–2026 Ford Bronco 4WD, restricted to rigs running 2.5 to 3.5 inches of suspension lift. The bolt-on swap needs no modification, and the POM ball joints widen the arm's range of travel while staying greaseable. Broncos with Ford's HOSS 4.0 suspension are not covered. Grease the ball joints before driving.

Lift range decides this one: the arms are made for 2021–2026 Ford Bronco 4WD models carrying 2.5 to 3.5 inches of suspension lift, and Broncos equipped with Ford's HOSS 4.0 suspension system are excluded. Fitment otherwise spans Base, Big Bend, Black Diamond, Outer Banks, Badlands, Wildtrak, Everglades, and the Heritage and Stroppe editions. Each arm is forged aluminum in one piece, so there is no welded joint to crack, and the POM ball joints take grease and articulate farther than the factory arm. Plan on 1-2 hours with the downloadable installation guide.
