What is the main advantage of using RockJock RockNuts over traditional jam nuts?

RockJock RockNuts use a tapered collet design to bind the nut and bung together, creating a secure connection that eliminates the need for jam nuts. This prevents loosening that can occur with traditional jam nuts, especially in high-stress applications.

What size tubing is the included bung designed to be welded into?

The steel weld-in bung is designed to be inserted into tubing with a 1 1/2 inch outer diameter and a 0.188 inch wall thickness.

What is the thread size and direction of the nut included in this kit?

The kit includes a steel nut with a 1-inch diameter and a 14-thread-per-inch right-hand thread.

Product Details

This RockJock RockNut kit gives you a steel nut with a 1-inch, 14-thread-per-inch right-hand thread and a steel weld-in bung. The nut has a female taper, and the bung is designed with a male taper that intersects with the nut's taper. This setup is intended for suspension fabricators who are working with 1 1/2-inch outer diameter tubing that has a 0.188-inch wall thickness.

The idea behind these RockNuts is to replace traditional jam nuts, which can loosen over time, especially in demanding off-road conditions like rock crawling or racing. When you tighten the nut onto the bung, the tapered surfaces bind together, creating a strong, locked connection. This not only keeps your suspension joints from binding up in their brackets but also prevents the arm and the joint from damaging each other due to looseness. The nut comes with a black zinc plating for corrosion resistance, while the bung is raw steel, ready for welding into your control arm tubing.
