Eliminator Torsion Axles

Suspension travel and shock absorption are handled by four cords inside the axle housing. As the wheel moves up or down, the rubber cords compress, offering a progressive rate of resistance. With a progressive "spring" rate, small bumps are handled by a soft initial rate, while larger bumps use a stiffer rate. This makes for a smoother ride over all types of roads.
