Product Description

The RockJock RJ-182500-101 Johnny Joint Rear Upper Control Arms are a heavy-duty, double adjustable replacement for the factory rear upper control arms on 2021-2025 Ford Bronco models. Fabricated from 1.625 in. O.D. x .250 in. wall DOM steel tubing and equipped with 2 1/2 in. Johnny Joints at both ends, these arms provide over 30 degrees of articulation per joint - far exceeding the flexibility of the factory stamped steel arms. The 1 1/4 in. RH/LH threaded ends allow arm length to be adjusted without removing either end from the vehicle, making pinion angle correction and axle alignment simple and precise after a suspension lift installation.

These arms are a direct bolt-on replacement using factory mounting hardware and are compatible with stock-height builds as well as lifted Broncos. They are designed for all standard Bronco trim levels - note that the Raptor model uses a different suspension configuration and requires a separate application. Sold as a pair covering both driver and passenger side rear upper positions, and backed by RockJock's 2-year limited warranty.
