What more, you need to find the right hitch ball. The same is also essential in the rating of the receiver hitch.

Choosing the right trailer ball involves considering the GTWR of a hitch ball. Other significant details include the thickness of the mounting platform, the trailer hitch ball sizes, and the hole diameter. These must as well be taken into consideration 100%.  The trailer ball is classified as an attachment providing a connection between the hitch and the trailer. The specifications include a shank diameter, shank length, ball diameter, and shank rise.

Measuring the Trailer Ball

There are certain factors, as mentioned, that need to be considered in mind. These include the shank length, ball diameter, shank diameter, and the rise.

Specifying the Torque

Also, include having an understanding of the torque. They are mainly divided into ¾ inch shank measuring 160 ft.-lbs, 1-inch shank measuring 250 ft-lbs, 1 ¼-inch shank measuring 450 ft. lbs, and a 2-inch shank measuring 4, 550 ft. lbs.

Determining The Trailer Hitch Ball Sizes

The way to determine the right trailer hitch ball sizes are as follow:

Shank Length. This is known as the length of the shaft extending beyond the mounting base of the hitch ball. A shank that is long enough should be used as it extends beyond the thickness of the drawbar mounting tab. The purpose of which is to ensure that there are enough threads that can fasten the ball to the mount.

Ball Diameter. Make an effort to check on the topmost portion of the trailer coupler. This must be done to know the size of the ball diameter needed. Light commercial and recreational hitch balls can come in different sizes that include 1 7/8 inches, 2 5/16 inches, and 3 inches. The lighter trailers normally require the use of smaller hitch balls. You need to consider matching the right hitch ball to the trailer.

Shank Diameter. This is considered as the threaded shaft diameter inserted by way of the ball mount. The shanks can come in different sizes of 5/8 inches, ¾ inches, 1 inch, and 1 ¼ inch. The capacities can range between 7,000 lbs to 17,000 lbs.

Rise. The shank, in particular to its height, can be utilized to raise the back of the trailer. It can be leveled in the chance that there is a “rise” and “drop” of the ball that is also inadequate.

Moreover, the diameter of the hitch ball could be matched to the size of the trailer coupler. Such an undersized ball can fall and loosen up. The shank diameter which is the width of the threaded shank needs to be equal in its hole diameter. The shank length which is the distance from the bottom to the top of the shank should have minimum 2 threads. These should be visible when the nut has already been tightened. The shank height or the shank rise must be used to accurately level the trailer. This is when there is an improper “drop” or “rise” in the trailer ball mount.
