The present invention relates to a vehicle towing hitch or trailer coupler method of reducing bounce or shock motion from being transmitted between the towing vehicle and towed vehicle or trailer, thus allowing a towing vehicle to tow a trailer over a rough road while reducing the bounce effect of the trailer from being transferred to the towing vehicle and visa versa. Said towing hitch or trailer coupler further comprises two or more parallel arms attached to one or more torsion axle as the preferred means to both support the towing load and also dampen the road bounce and shock load. The dampening means may be mounted on the towing vehicle or the trailer coupler.
