RockJock 2021+ Bronco Rear Frame Johnny Joint 2 1/2in Forged 1 1/4in-12 LH Threads 74mm x 16mm Ball

Starting with a forged body, this RockJock Johnny Joint is built for fabricators and suspension system builders looking for serious articulation. It offers a full 30 degrees of unrestricted movement in any direction, which is notably more than the typical 22 degrees you'd get from a standard heim joint. This extra range comes from the high-density urethane bushings that cushion the inner ball, providing a level of dampening that heim joints can't match.

The heat-treated center ball is designed with cross-drilled holes to allow for easy lubrication through the included zerk fitting. Internally, the joint is secured by two heavy-duty, heat-treated side washers and a snap ring. This specific joint is made to fit the frame side of the rear control arms on 2021 and newer Broncos. It features a 2 1/2 inch diameter body, 2.3 inches of 1 1/4 inch-12 left-hand threads on the shank, and a 74mm wide ball with a 16mm hole for the thru-bolt. The gold zinc plating helps resist corrosion.
