A torsion trailer coupler is affixed to a trailer between the tongue and an adjustable coupler. The torsion trailer coupler has a trailer side that affixes to the trailer and a coupler side that affixes to the adjustable coupler. The trailer side has torsion tubes that carry torsion bars and the coupler side has torsion tubes that carry torsion bars. The torsion bars between the trailer and coupler side are connected with torsion arms. The torsion trailer coupler moves between an unloaded position where the torsion bars and arms are at rest and a loaded position where force is applied between the sides and the torsion bars rotate about their central axes. The torsion bars, arms and sides cooperate to absorb transient forces between a towing vehicle and the tongue of the trailer.
