RockJock’s weld-on 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 polyurethane 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, chromoly side washers and a snap ring. The outer shell is weldable 180″ wall machined chromoly tubing that is fitted with a zerk fitting for greasing. This specific joint is a 3″ o.d. and features a 3.250″ mounting width and a .750″ thru bolt hole.
