The invention provides a kit of parts, and a procedure for welding together such parts, to provide a strong trailer hitch for cars. The components of the hitch are such that they can be welded together in various different configurations so as to fit the large majority of cars, station wagons, pickup trucks and vans manufactured in North America. One feature of the hitch is that the socket member which receives the ball assembly is welded into a central tubular member forming part of a cross member of the hitch, and is weldable within this tubular member in different positions to suit required positioning of the ball member. Another feature is the use of two angled side members each having two legs the end portions of which are each sized so as to be insertable selectively into the outer ends of tubular arms which form the main part of the central cross member, the two legs of the angled side member being of differing lengths so that different hitch configurations are obtained by inserting a longer or shorter leg into the respective tubular arm of the cross member.
