Understanding U Haul Trailer Ball Size Factor

As you can already see from the chart given above, there’s the same minimum size of hitch ball required for all the trailers that U haul provides for rent. However, the weight capacity for the balls is different and something you must highly consider.

For example, the smallest option here is a 4×7 utility trailer. And you can see how it needs at least a 2000-pound hitch ball rating. U haul 5×9 trailer ball size requirements are also similar.

Then u haul 6×12 trailer hitch ball size requirement is also the same, but this time the weight rating surges up to 3500 pounds. However, the heaviest one called Auto Transport requires the same size but almost double-weight rating hitch ball.

If you want to get a hitch ball that will go with absolutely any cargo trailer of U-Haul, it’s the 1-7/8” or 2” hitch ball with a 5000-pound weight rating.

Keep in mind that the hitch ball must be at least the same weight you’re planning to tow or more than that. The hitch ball rating factor is significantly important as the receiver hitch rating, so you cannot ignore it.

To determine if a hitch ball is a perfect fit, measurements of shank length and diameter are necessary. Because larger hitch balls come with a shank diameter that’s also large, these setups are great for heavy weight pulling.

This is How You Determine The Hitch Ball Size

  1. The most important consideration for hitch ball selection has to be weight capacity. Get a hitch ball that has a ball capacity more than the gross trailer weight. Only then the trailer will be pulled efficiently.
  2. You must match the size of the coupler to the hitch ball diameter for a safe towing experience. It needs to be a perfect match for the trailer ball diameter.
  3. The hitch ball selection will also need you to consider the ball hole size so that you can get a matching shank for it. You cannot mess up the shank diameter matching ball hole. Otherwise, the whole towing experience will be wobbly.
  4. Getting a perfect ball mount is also important. This will make sure the connection between the U-Haul trailer and your tow vehicle is stable at all times. For a perfect ball, mount selection considers the difference between the height of the hitch and the height of the coupler. The difference is the drool required for the ball mount.
