Can a 1-7/8 inch Hitch Ball be Used with a 2 inch Coupler on Trailer  


I just bought a used trailer with a 2 inch coupler. My tow set up has a 1 7/8 ball. Is that close enough or do l need to get a 2 inch ball?


Expert Reply:

If your trailer has a 2 inch coupler then you definitely need to go with a 2 inch ball. Even though 1/8 inches doesn't sound like very much, it is enough that your trailer could come uncoupled under the right conditions.

I have attached a link to our selection of 2 inch hitch balls for you to filter through. You will just need to be sure that the shank of the hitch ball has the correct diameter and that it is long enough for your ball mount.

For example, the popular Curt 2 inch Hitch Ball # A-90 has a shank that is 1-1/4 inches in diameter x 2-5/8 inches long.
