Most hitches employ a removable drawbar, which holds the hitch ball. The bars come in two sizes: 1.25 inches (for lightweight pop-ups and bike racks) and 2 inches (for heavy loads). Hitch balls come in three main flavors: 17/8 inches, 2 inches and 25/16 inches. Generally, the bigger the ball, the more weight it can support. If you own two or more trailers that call for different ball sizes, I recommend buying separate drawbars with the proper balls permanently attached.
