Built for Short Trailers in Heavy Distribution

The TR-X mechanical steering system is used primarily for short trailers in heavy distribution transport such as tippers, milk-distribution, and construction transport. It steers the first and last axle of a three-axle trailer, with the first steered axle turning in the opposite direction of the last steered axle.
