Product details
RockJocks narrow forged Johnny Joints for fabricators and suspension system builders offer up to 40 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 designed to fit the axle side of the 2021 and up Broncos rear control arms and feature a narrow 2 1/2 in. diameter joint body, fitted with a zerk fitting for greasing, 2.3 in. of 1 1/4 in.-12 right hand threads on the shank, and a 70mm mounting width ball with a 16mm thru bolt hole. Finished in gold zinc plating. Johnny Joint® Rod End; 2.5 in.; Narrow Forged; 1.25 in.-12 RH Threads; 70mm x 16mm Ball; Johnny Joint® Rod End
