Rock Jock Johnny Joint Front-End Housing Kits

Rock Jock Johnny Joint front-end housing kits replace the upper control arm bushings of your factory differential housing for maximum articulation of your suspension. These kits include Johnny Joint inserts to switch out with the rubber bushings on the axle housing, greasable bolts, and installation tool. Rock Jock's Johnny Joints are durable high-articulation urethane suspension joints featuring 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. Show Less
