RockJock 2021+ Bronco Johnny Joint Rear Upper Control Arm Set Steel Adjustable

RockJock’s Johnny Joint Billet Aluminum RockNut Rear Lower Control Arm Set for the 2021-up Bronco provides you with extremely heavy duty, adjustable length control arms to replace your factory control arms. Adjustable control arms are a must for aligning lifted vehicles to get your pinion angle specs. in check!

These arms are CNC machined from 7075-T6 aluminum, feature our patent pending RockNut locking nut technology and our 2 1/2 in. Johnny Joints with massive 1 1/4 in. RH/LH threads!

Johnny Joints, the original and most durable high-articulation urethane suspension joint on the market, feature a smooth steel ball that pivots inside a proprietary urethane shell to provide over 30 degrees (per joint) of quiet, shock dampening articulation - without the excessive deflection found in soft rubber-based flex joints. Johnny Joints deliver a smooth, comfortable on-road ride with the ultimate in off-road capability. They are so trusted, that they are used by multiple commercial suspension companies, for both street and off-road suspension systems. 

Arms are fully greasable, fully adjustable and feature machined-in wrench flats. Finished in clear anodize on the arms and gold zinc plating on the Johnny Joint ends.
