Trailer hitch ball sizes
There are four key factors that must be considered when selecting a trailer hitch ball for your towing setup.
1. Weight rating.
2. Coupler size.
3. Hole size.
4. Platform thickness.
To learn more about each of these factors, see the panel below. The diagram to the right shows the various measurements of a trailer ball, which may be referred to in the following sections.
1. Weight rating
Before selecting a trailer hitch ball, it is important to know how much weight you’ll be towing. Each trailer balls is rated to certain gross trailer weight capacity and tongue weight capacity. The gross trailer weight is the total weight of the trailer, while the tongue weight is the weight specifically at the coupling point.
Remember, your towing capacity is always limited by the lowest-rated towing component, whether that’s the vehicle, the trailer hitch or the tow ball.
2. Coupler size
The second important factor to consider is the size of your trailer coupler. Many couplers are adjustable, but only within a limited range.
When selecting a tow hitch ball, choose one with a ball diameter that matches the coupler size. It is extremely dangerous to attempt to tow without a matching tow ball and coupler.
3. Hole size
'Hole size' refers to the diameter of the mounting hole into which the trailer hitch ball shank is inserted. The diameter of the hole must be no more than 1/16” larger than the diameter of the shank.
If you already own a ball mount or bumper with a mounting hole that is too larger, you may be able to make up the difference using a CURT reducer bushing of the appropriate size.
4. Platform thickness
The thickness of the mounting structure is also vitally important, whether that mounting structure is a CURT ball mount, fixed-tongue trailer hitch or a bumper. The platform must be at least 3/8” thick to be considered safe for towing.
If the mounting platform is too thick, CURT trailer balls are available with a variety of shank lengths, including up to 3-1/2".
