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

The RockJock Johnny Joint offers up to 30 degrees of movement in any direction, compared to the typical 22 degrees of a heim joint. It also includes urethane bushings for cushioning, which a heim joint lacks.

How is this rod end lubricated?

The heat-treated center ball is cross-drilled for internal lubrication, and the entire joint can be easily greased externally via the zerk fitting located on the outer shell.

What are the dimensions of this specific Johnny Joint?

This joint has a 2-inch outer diameter, a 2-inch mounting width, and a 0.4375-inch (7/16-inch) hole for the thru-bolt.

About this part

Product Details

If you're building a custom suspension setup, especially for off-road use where you need a lot of flex, a weld-on rod end like this Johnny Joint from RockJock is a solid choice. It's designed to give your suspension arms and links a wide range of motion, letting your wheels articulate over obstacles without binding.

What sets this joint apart is its ability to move up to 30 degrees 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, offering a bit of cushioning that heim joints can't match. The center ball is drilled for lubrication, and you can easily grease the whole assembly through the zerk fitting on the outer shell, which is made from weldable DOM tubing. This particular joint has a 2-inch outer diameter, a 2-inch mounting width, and a 7/16-inch hole for the thru-bolt.
