Xuxing XR019 6 mm Threaded Guitar Tremolo Arm, Chrome Metal, 7.7-Inch

The 6 mm threaded connection gives this replacement tremolo arm a specific fit to check against your guitar’s bridge. Its chrome metal finish suits players looking for a matching replacement, while the included tip provides a finished contact point. The arm measures about 7.7 inches long. Thread size is the key detail to confirm before choosing it.

These details make this a targeted replacement rather than a universal bar. The listing describes it for electric guitar tremolo bridges and references Stratocaster electric guitar tremolo systems, but it specifies a 6 mm thread—not compatibility with every Stratocaster or every bridge. Match the thread diameter to your existing arm or the bridge’s specifications. The arm itself measures about 5 mm in diameter, while the stated insert diameter is about 6 mm, these measurements describe different parts of the arm, so use the thread size when checking the bridge connection.

How to use it

This is intended to fit a threaded tremolo bridge. Before installation, compare the bridge’s thread specification with the listed 6 mm diameter and make sure the arm’s thread is the right match. If you still have the original arm, its connection can help you identify what replacement type you need. Don’t treat the chrome color or Stratocaster reference as a substitute for checking the thread: a similar-looking arm with a different connection may not fit.

Once fit is confirmed, the arm is used as the lever for a compatible guitar’s tremolo system. Its 7.7-inch length gives you a defined arm size to compare with your current setup when selecting a replacement. The listing does not specify an adjustment mechanism or additional hardware, so this is best considered a single threaded arm rather than a complete bridge or tremolo assembly. It makes sense if you need a chrome replacement and have confirmed that your bridge uses a 6 mm thread. It’s not for you if your bridge requires a different thread size or a different arm connection.

In the box

The package includes one single tremolo arm with a plastic tip. It is not described as including a bridge, mounting hardware, or extra replacement tips. If you are replacing a missing or damaged arm, that focused package keeps the purchase centered on the arm itself, if your bridge also needs repair or other parts, those are not listed as included.

Is it worth it?

The Xuxing XR019 is worth considering when the thread specification is the main thing you need to match and a chrome metal arm is appropriate for your guitar. Its useful buying details are clear: 6 mm thread diameter, about 7.7 inches of arm length, and a plastic tip. The practical tradeoff is that those measurements make fitment specific. Compared with choosing an arm based only on appearance or a broad guitar-family label, matching the actual bridge thread is the more reliable way to narrow down a replacement. If the thread is confirmed, this gives you a straightforward single-arm option, if it is unknown, identifying the bridge connection first is the better next step.
