There are many different available sizes of trailer balls and ball mounts on the market, so simply walking into your local Curt dealer and picking the first one you see isn’t always going to be your best option. There are three things that you need to consider when selecting a ball mount; how much weight you are going to be towing, what size receiver tube the trailer hitch has, and finally how much rise or drop is needed to provide a level and safe towing set-up.

To determine the amount of weight that you’re going to be towing, you can look at the weight rating plate on your trailer. If your trailer isn’t equipped with a weight rating’s plate you could take it to a certified scale. Our trailer weighed in at 2,500 lbs.

The hitch that we have on this vehicle is a Class 5 Xtra Duty trailer hitch capable of handling 15,000 lbs. It also has a two-inch receiver tube which lets us know that we need a ball mount with a two-inch shank.

Now we need to determine how much rise or drop is needed to provide a level and safe towing set-up. To do this we need a receiver height measurement. Take the measurement from the ground to the top inside edge of the receiver tube. Our measurement here is 21.75 inches.

The next measurement we need is the coupler height. To do this, we’re going to use the hand level on the trailer jack to level out the trailer, and then take the measurement from the ground to the bottom of the coupler. Our measurement here is fifteen and a half inches.

Now that we have both of our measurements, we need to subtract our receiver height from our coupler height. If that number is negative, that will show you how much drop you need. If that number is positive, that will show you how much rise. We take our coupler height of fifteen and a half inches and subtract our receiver height of twenty-one and three-quarter inches, leaving us with a negative six point two five. Round that to the nearest number and that gives us a negative six inches. This lets us know that we need a ball mount with a six inch drop.

Now that we’ve determined how much drop we need, we can move on to selecting the trailer ball. Typically, coupler manufacturers will stamp or label the correct ball size that they’re designed to work with right on the coupler itself. If you ever find that the trailer ball that the coupler is designed to work with doesn’t fit, don’t panic. Most couplers are adjustable, so simply adjusting the coupler will do the trick. To do this, simply tighten or loosen the adjustment nut located underneath the coupler.
