RJ-301000-103 - Jeep JL/JT Frontend Housing Johnny Joint® Kit

SKU RJ-301000-103


The RockJock® Johnny Joint Differential Housing Kit replaces the front differential housing upper control arm bushings on your Jeep JL Wrangler 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.
