Fit of Adjustable Ball Mount on 2015 Chevrolet Silverado 3500

Expert Reply:

The ball mount you referenced, Fastway Self-Locking Adjustable Aluminum Ball Mount # DTALBM7025, fits 2-1/2-inch hitches and its locking pins will engage with the hitch pin holes on a 2-1/2-inch receiver tube. If you have a similar ball mount made for a 2-inch hitch, such as # DTALBM6600, its pins will not extend out far enough to engage with the holes on a 2-1/2-inch receiver. You cannot use a reducer sleeve like # 58102 to use a 2-inch ball mount in a 2-1/2-inch hitch.

For reference the linked page will show you all hitches offered for the 2015 Silverado 3500. You can use the drop-down menu at the top of the page to select your vehicle style to then see compatible hitches. For example, Curt hitch # C15860 fits both 6-1/2-foot-bed and 8-foot-bed versions of the 2015 Silverado 3500.
