RockJock's forged 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 designed to fit the frame side of the 2021 and up Bronco's rear control arms and feature a 2 1/2 inch diameter joint body, fitted with a zerk fitting for greasing, 2.3 inch of 1 1/4 inch-12 left hand threads on the shank, and a 3.150 inch mounting width ball with a .718 inch thru hole.
