RockJocks weld-on Johnny Joints(R) 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(R) 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. The outer shell is weldable .180 in. wall machined DOM tubing that is fitted with a zerk fitting for greasing. This specific joint is a 2 1/2 in. o.d. and features a 2.465 in. mounting width and a .625 in. thru bolt hole. This ball center does not have a flange on one side for use in front trac bar applications.
