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, black zinc plating on the RockNuts and gold zinc plating on the Johnny Joint ends.
