Our Camburg threaded bungs are machined in-house from aircraft quality 4130 chromoly, not cheap mild steel or imported low quality material. These are a stepped design to match the OD of the tubing being used with a chamfered fillet for MIG or TIG welding them in. We offer these is a wide range of sizes for different heim/rod end sizes and tubing sizes. You can use these to custom build tie rods, upper control arms, lower and upper links/trailing arms among many other applications. We offer them in both right-hand and left-hand versions depending on the size.
