What is this on my trailer?

I just bought a Calkin’s double axle trailer. It has these bars and the bracket on it. I’ve never seen this before. Can anyone tell me what these are?

It does look like a leaf spring but it’s not the right size. And why would it be there instead of on the spring pack? I’m going to take it off but wanted to see if someone had a thought on what it’s there for?
