ABSTRACT:
An attachment for a trailer hitch to eliminate essentially all the play in a coupling of a trailer hitch head to a trailer hitch drawbar includes an adjustable spacing means to space the hitch head from the drawbar. The distance between the two ends of the attachment is adjustable in a direction parallel to the longitudinal axis of the trailer hitch. One end of the attachment is mounted on the drawbar and the other end of the attachment is mounted on the hitch head. When the spacing means is adjusted the hitch head is moved relative to the drawbar in a direction parallel to the longitudinal axis of the hitch to eliminate essentially all of the play in the hitch.
