A cam locking removable hitch assembly apparatus and system is described. The apparatus generally includes a hitch-ball shank in engagement with a shank sleeve that is in engagement with an outer sleeve. A nut is in threaded engagement with a lower portion of the hitch-ball shank securing the outer sleeve around the shank sleeve. Shank lugs, on a lower portion of the hitch-ball shank, engage with shear lugs internal to the shank sleeve when the hitch-ball shank is rotated with respect to the shank sleeve. Cam's on the upper portion of the hitch-ball shank engage with cam grooves on an upper portion of the shank sleeve, thereby locking the hitch-ball shank within the shank sleeve. The hitch assembly apparatus can be connected to a frame that is secured in a bed of a truck forming a cam locking removable hitch assembly system.
