RockJock Front End Housing Johnny Joint Kit

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, greaseable 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 in.. 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. Joints are fully greaseable and are finished in clear zinc plating.
