What is the main advantage of a Johnny Joint over a heim joint?

Johnny Joints offer more range of motion, typically 30 degrees compared to a heim joint's 22 degrees. They also provide cushioning through urethane bushings, which a heim joint cannot offer.

How is the Johnny Joint lubricated?

The heat-treated center ball is cross-drilled for lubrication, and the outer shell is fitted with a zerk fitting for external greasing.

What material is the outer shell made from?

The outer shell is constructed from weldable .180-inch wall DOM tubing, making it suitable for custom fabrication and suspension builds.

About this part

Product Details

This RockJock weld-on Johnny Joint is designed for fabricators and suspension system builders working on the rear frame of 2021 and newer Broncos. You get a 2.5-inch diameter, weldable DOM tubing outer shell that houses a 74mm wide, 16mm thru-bolt hole center ball. This joint is built to give you 30 degrees of unrestricted movement in any direction, which is more than you'd get from a standard heim joint.

Inside, high-density urethane bushings surround the heat-treated center ball, providing cushioning that heim joints can't match. The center ball is cross-drilled for lubrication, and the internals are secured by two heavy-duty, heat-treated side washers and a snap ring. The outer shell is made from .180-inch wall DOM tubing and includes a zerk fitting for easy external greasing.
