ABSTRACT:
An anti-sway device for conventional trailers, which essentially takes the place of the shank member of a conventional trailer hitch, is described. The shank assembly is comprised of an elongate square member coupled to a conventional hitch receiver of a tow vehicle. Attached to the rearward end of the square member is a pivot member with rearward diverging links connecting it to another somewhat wider pivot member to which a conventional ball mount is attached. The ball mount is further linked to the towed trailer such that the tongue of the trailer is fixed to the ball mount about a vertical axis. This arrangement results in the trailer pivoting about the resulting center of rotation of the converging links, which is substantially forward of the ball of the trailer hitch. Moving the pivot point forward, such as that found on a fifth wheel trailer, reduces sway and enhances the stability of the coupled trailer and tow vehicle.
