Tractor Single Drive Axles is an axle configuration in which there is only one drive axle. This arrangement is used in lighter trailer-tractor combination. It has less maintenance, original cost and less weight than other configurations but also has less stability, efficiency, dependability and fault tolerance than tandem or tri-axle system.
Check with your Freight Brokers if this configuration is good and safe for the freight that you intend to carry. Most freights expect trucks to have a tandem or tri-axle drive wheel configuration.
