RockJock 2021+ Bronco RockNut Billet Aluminum Johnny Joint Rear Upper Control Arm Set Adjustable

The RockJock RockNut Billet Aluminum Johnny Joint Rear Upper Control Arm Set is built for your 2021-up Ford Bronco, especially if you've lifted it. When you lift a vehicle, the angles of your suspension components change, and these adjustable control arms let you dial in your alignment, particularly your pinion angle, to get everything back in spec. This set features double-adjustable arms, which is a real time-saver during alignment because you don't need to remove either end of the arm from the vehicle to make adjustments.

These arms are CNC machined from strong 7075-T6 aluminum, making them tough yet lightweight. They incorporate RockJock's patent-pending RockNut locking nut technology and massive 2 1/2-inch Johnny Joints with substantial 1 1/4-inch right-hand and left-hand threads. The arms are fully greasable, meaning you can keep the joints lubricated for long life, and they have built-in wrench flats for easier adjustment. The clear anodized finish on the arms and gold zinc plating on the Johnny Joint ends offer good looks and corrosion resistance.

This set is designed to replace your factory rear upper control arms. Having adjustable control arms is pretty much a requirement for properly aligning a lifted Bronco, and this double-adjustable design makes the process much more straightforward. You'll want to refer to the manufacturer's installation instructions for the specific steps involved in adjusting and installing these arms to ensure your alignment is set correctly.
