Q: What is the height on the ball end?

The ball is a regular 2 inch ball. Height depends on the receiver hitch

Q: ball marks on top says 2 am i missing something

It’s a 2 5/16” ball not a 2”

Q: Whats the socket size for nut?

The nut on a hitch ball with a 1-1/4 inch shank takes a wrench with a 1-7/8 inch socket. A hitch ball with a 1 inch shank will take a wrench with a 1-1/2 inch socket. So the best tool for this ball is a 1 1/2” box end wrench.
