RockJock’s Johnny Joint Front Axle Housing Kit replaces the front differential housing upper control arm bushings on your Jeep JL Wrangler, JL Unlimited or JT Gladiator with Johnny Joint rod ends from RockJock, allowing you to get maximum articulation out of your front suspension!
This kit includes Johnny Joint inserts that replace the rubber bushings on the axle housing, greasable bolts and installation tool.
RockJock’s Johnny Joints are the original and most durable high-articulation urethane suspension joint on the market. Johnny Joints 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. Learn more here.
Joints are fully greasable and are finished in clear zinc plating
