Rock Jock Threaded Weld-In Bung with Jam Nut Thread Suspension Rod End Bearing

The Rock Jock Threaded Weld-In Bung with Jam Nut is a weld-in threaded bung for suspension rod ends. It lets custom vehicle builders fabricate their own control arms, links and adjustable bars. Each bung is designed for use with Rock Jock Johnny Joint rod ends or any other rod end with a matching thread. It is also known as a threaded weld bung, rod end bung or tube insert.

Key Features:

• CNC machined in-house from premium steel hex stock
• Hex shape instead of round, which makes bar adjustment easier with a wrench
• Hex size is kept small, and a matching small-hex jam nut is included so the bung and nut share the same wrench size
• Raw steel bung ready for welding, with a zinc-plated jam nut
• Sized for commonly available tubing, so builders can source the tube, cut it, install the bungs and weld
• Available in right-hand and left-hand thread options for a range of thread sizes

Rock Jock's threaded bung and jam nut sets have been part of its Johnny Joint product line since 1996. They suit fabricators building adjustable suspension links, with a jam nut that locks the rod end alignment once it is set. Choose the thread direction and size that match your rod end and tubing.
