An adjustably extensible trailer hitch assembly changing a trailer hitch which allows a driver trying to back up into the correct position to conveniently attach a trailer hitch more room for error. The trailer hitch provides a top plate assembly that attaches to standard holes provided in most factory bumpers. The top plate provides a vertically oriented pivot pin. A hitch receiver having a square steel tube body is pivotally mounted on the pivot pin. A hitch extension arm having an elongate pivot pin opening is also pivotally mounted, and is slidably carried by the hitch receiver. The extension arm carries an end plate on its rearward end, having a matrix of bolt holes which are adjustably attached to a ball mount plate also having a matrix of bolt holes. The ball mount bracket can therefore be attached to the extension arm at a variety of elevations. A U-lock pin, carried by the top assembly, may be lifted to an upper position which allows the hitch receiver to pivot, and is moved by gravity to a lower position preventing the hitch receiver from pivoting when the receiver is perpendicular to the bumper. A locking bolt prevents the hitch extension arm from extending, and also prevents the U-lock pin from moving to the upper position.
