A hitch ball (20) with a mating first set of shells (25a and 25b) and optionally a second set of shells (27a and 27b) to increase the diameter of the ball to accommodate various sized hitch assemblies (11) are described. In a preferred form detents (25e and 25f) in the first set of shells are provided in a recess (23) in the ball. Detents (27c and 27d) are provided on the detents (25e and 25f) of the first set of shells. The invention provides safe and effective mounting of the sets of shells on the hitch ball and prevents the shells being used on a conventional hitch ball which might not be rated for the increased capacity provided by the larger ball size.

An improved ball for a tow bar assembly mounted on a vehicle which comprises: (a) a spherical ball with a shank extending from an axis of the ball for mounting on a tongue of the tow bar assembly; and (b) opposed hemispherical half shells mounted on and mating with the ball so as to encase the ball, means on the shell to hold the half-shells on the ball wherein the shells can move around the axis of the ball and wherein the shells provide an enlarged standard diameter for the spherical ball which fits into a trailer hitch assembly and wherein the shells are secured in place on the ball by the hitch assembly.
