Q: Does the RoySuper electric trailer dolly support a 2-5/16 inch hitch ball in addition to the standard 2-inch ball?

A:
Yes. The RoySuper electric trailer dolly supports both 2-inch and 2-5/16 inch hitch balls. If you choose to install a 2-5/16 inch hitch ball, please ensure that the ball features a 1-inch threaded shank for proper fitment and secure installation on the dolly.

When using a 2-5/16 inch ball for larger RV or boat trailers, carefully check the trailer weight, tongue load, and balance. Make sure the trailer’s load does not exceed the maximum towing capacity of the RoySuper electric trailer dolly to ensure safe operation and optimal performance.
