I believe there are only 3 standard sizes, and of them ONE (something like 2 5/8" is for the ginormous rigs)
For the others, there is the 2" and the 1 7/8".
IF YOU HAVE SUCCESSFULLY locked it with a 2", that is the one you need. You don't need to change anything.
If you had been using a 1 7/8" ball, the coupler will "lock" around it, but it could pop loose when towing.
BUT if the coupler needed a 1/78, there is no way a 2" would fit and lock.
So... i repeat... IF YOU HAVE SUCCESSFULLY locked it with a 2", that is the one you need. You don't need to change anything.
