Can you identify this part?

Shock mount?

I think that is one end of the shock mount.

It's the part of the shock mount for vertical shocks.
And, more important, your brake assemblies are mounted upside-down and backwards, and need to be changed to the correct orientation. It's a right-hand brake assembly mounted inverted on the left side of the trailer.

Thanks for the heads up on the brakes. I will make the correction.

Another good reason to post pictures along with your question. In this case Overlander helped identify a different, and potentially a more serious issue than the one asked about.

This is another example of the helpfulness of those on this site. Thanks to all who regularly contribute their knowledge and wisdom, there are a lot of you out there.
