Three factors to consider

There are three main things to consider when selecting a trailer hitch ball mount: how much weight you are going to be towing, what size receiver tube your trailer hitch has and how much drop or rise your ball mount will need (below).

Trailer weight vs capacity

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.

Hitch receiver size

Next, determine what size shank you will need. 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.

How to determine drop or rise

After you know how much weight you will be towing and the size of your receiver tube, you will need to determine the drop or rise necessary for your trailer.

Drop or rise is the amount of height difference between the trailer and your tow vehicle, whether that difference is positive (rise) or negative (drop).

The diagram offers a quick explanation for how to determine your needed drop or rise. Take the distance from the ground to the top of the inside of your receiver tube opening (A), and subtract it from the distance from the ground to the bottom of the trailer coupler (B).

B minus A equals C, the drop or rise.
