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

The Johnny Joint offers a greater range of motion, allowing for 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 do I lubricate this rod end?

This rod end is externally greased. You can use a standard grease gun on the zerk fitting located on the outer shell to lubricate the internal center ball, which is cross-drilled for easy grease distribution.

What material is the outer shell made from?

The outer shell is made from weldable DOM (Drawn Over Mandrel) tubing with a 0.180 inch wall thickness, providing a strong and reliable base for welding onto your custom suspension components.

About this part

Product Details

If you're building a custom suspension system, especially one that needs a lot of flex, this weld-on Johnny Joint rod end from RockJock is a solid choice. It's designed for fabricators who need to create their own suspension arms or links and want more movement than a standard heim joint can offer. This joint allows for a full 30 degrees of movement in any direction, which is a notable increase over the typical 22 degrees you'd get from a heim joint. That extra range helps keep your tires planted on uneven terrain.

What sets the Johnny Joint apart is its construction. It uses high-density urethane bushings around the center ball, which provide a bit of cushioning that a heim joint can't. The heat-treated center ball is cross-drilled so you can easily lubricate it through the zerk fitting on the outer shell, keeping it moving freely. It's held together with heavy-duty, heat-treated washers and a snap ring. The outer shell itself is made from weldable DOM tubing, giving you a strong base to attach to your custom fabrication.

This particular joint has a 2-inch outer diameter and a 2-inch mounting width, with a 0.500-inch hole for the thru-bolt. It's externally greased, meaning you can easily service it with a grease gun to ensure longevity and smooth operation.
