Do Trailer Dolly Hitch Balls Have to Match the Ball Size of Coupler

Question:

I have a trailer dolly that has a 2inch ball with a 3/4inch shaft. I just purchased a new trailer that takes a 2-5/16foot ball. I need a 2-5/16inch ball with a 3/4inch shaft ball for the dolly. Do you have one? Do they even make one? Thanks,

We don't sell a 2-5/16 inch hitch ball with a 3/4 inch shank, but since a tow dolly is only used for small trailer movements across a parking lot your current hitch ball should work just fine. When using a tow dolly the tongue weight alone of the trailer will keep the coupler attached to it. You do not have to use the exact same size hitch ball on a dolly. That is why frequently tow dollies will use a small sized hitch ball so that all coupler sizes can be used on them.

As long as the tongue weight of your new trailer is not more than what your dolly can handle you should be just fine.
