RockJock RockNut Kit Nut and Bung 1 1/4in LH Thread

If you're building or modifying suspension arms for rock crawling or racing, you know how frustrating loose jam nuts and binding suspension joints can be. The RockJock RockNut kit is an updated solution designed to eliminate these common issues. It replaces traditional jam nuts with a unique system that locks the suspension joint and the arm together with significant force.

This kit includes a 1 1/4 inch-12 LH thread steel nut and a steel weld-in bung. The nut has a female taper that mates with a male taper on the bung, which is designed to be welded into a 1 3/4 inch outer diameter by .188 inch wall thickness tube. When you tighten the nut onto the suspension joint, it forces the tapered components together, creating a solid lock on both the threads and the arm itself. This design helps prevent the suspension joints from binding up in their brackets and keeps the nut from loosening, which can save your suspension arms and joints from damage.

The nut comes with a black zinc plating for durability, while the bung is raw steel, ready for welding into your custom control arms. This is a well-built option for fabricators looking for a more reliable way to secure their suspension setups.
