RockJock's billet 4140 chromoly Johnny Joints for fabricators and suspension system builders offer 30 degrees of unrestricted movement in any direction as compared to 22 degrees on a common heim joint! Johnny Joint rod ends offer cushioning that a heim joint cannot provide via high-density urethane bushings that encase the inner ball. The heat treated center balls are cross-drilled for thru-bolt lubrication and the joint internals are retained with 2 heavy duty, heat treated side washers and a snap ring. This specific joint is a 2 1/2" diameter, fitted with a zerk fitting for greasing, 2 1/4" of 1 1/4"-12 right hand threads on the shank, and a 2.585" mounting width ball with a .640" thru bolt hole. Finished in clear zinc plating.
