As the inner shaft trys to rotate is squishes the rubber giving the spring. also happens to have killer ground clearance. Down side is they are very progrssive in the spring rate resulting in little travel. But very simple. Can be used in double axle configurations but is very sensitive to hitch ball height to get even axle loading. Not recomended for triple axle trailers. Torsion axles can be had in ratings of 8,000# per axle.
