Curt Manufacturing features top of the line towing products, and we are proud to be carrying there Towing Balls in our Inventory. This lightest duty trailer ball size, the 1 7/8 inch, is typically used for light duty utility trailers, jon boat trailers, motorcycle trailers and jet ski trailers. This category contains several options for the 1 7/8 trailer ball. Depending upon the ball mount you currently have, you can make a good selection to find the perfect fit below. We have 3/4 inch shank, and 1 inch shank options. This refers to the hole diameter of your ball mount. Each of these Curt Balls comes with the Lockwasher, and nut for securing them to your ball mount. Please be sure that the ball is properly tightened down with the correct tool before towing.
