What problem does the RockJock RockNut solve?

The RockNut is designed to prevent suspension joints from binding up in brackets and to keep jam nuts from loosening. This helps avoid damage to both the suspension joint and the control arm.

What are the dimensions of the bung for welding?

The steel bung is designed to be inserted into a tube with a 1 3/4 inch outer diameter and a .188 inch wall thickness. It has a raw, weldable steel finish.

What is the thread size and type for the suspension joint?

This RockNut kit features a 1 1/4 inch - 12 RH (right-hand) thread, which is the size that the nut will thread onto for securing the suspension joint.

About this part

Product Details

RockJock is known for making parts that hold up to serious off-roading. This RockNut kit is a smart evolution of how suspension joints are secured, especially for rock crawlers and racers. It replaces the old jam nut setup, which can bind up in suspension brackets and eventually loosen. That not only adds to your pre-event maintenance but can lead to the suspension joint and the control arm destroying each other if they aren't tight.

The RockNut uses a collet design. You get a steel nut with a female taper that mates with a male taper on the bung. This bung is designed to be welded into a 1 3/4 inch outer diameter tube with a .188 inch wall thickness, and it has a 1 1/4 inch - 12 RH thread. When you tighten everything down, the nut and bung bind together, and they also grip the threads of your suspension joint with significant force. This kit includes the steel nut, which has a black zinc plating for corrosion resistance, and a raw steel weld-in bung.
