How To Select Trailer Hitch Ball Mount
First, be sure to select a ball mount with enough gross trailer weight capacity to fit your trailer. Trailer weight is one of the most important aspects of towing, and you should never exceed the weight capacity of any component of your vehicle, trailer or trailer hitch setup.
Receiver tubes come in a handful of standard sizes, including 1-1/4, 2, 2-1/2 and sometimes 3 inches, so finding a ball mount to match is relatively easy.
