Product Details
RockJock is known for building tough suspension parts, and this Johnny Joint rod end is a prime example for fabricators and builders. It's designed to give you a full 30 degrees of movement in any direction, which is more than you'd get from a standard heim joint. The high-density urethane bushings inside help cushion the ride, something a heim joint just can't do. This particular joint is made to fit the frame side of the rear control arms on 2021 and newer Broncos.
The center ball is heat-treated and drilled so you can easily lubricate it through the zerk fitting. It's held in place by two heavy-duty washers and a snap ring. This joint has a 2 1/2 inch diameter body and features 1 1/4 inch - 12 right-hand threads on its shank, which measures 2.3 inches long. The ball itself is 74mm wide and has a 16mm hole for the thru bolt. It's finished in a gold zinc plating to help resist corrosion.
