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.
