Abstract
An interchangeable hitch ball assembly includes a mounting element to be secured to a vehicle and a hitch ball element to be secured to the mounting element. A post is on one of the mounting element and the hitch ball element, and a cavity is formed in the other. The post has a threaded head that screws past a threaded entryway in the cavity so as to reside in an interior chamber. The hitch ball can freely rotate relative to the mounting element when assembled, but it cannot be separated by axial movement. A fastener may be included to further secure the two members together. Several differently sized hitch balls may form a set to adapt to differently sized trailer tongues.
