2-speed rear axles

Tractor axle loading

As the fifth wheel moves weight is transferred between the axles on the power unit, or chassis. Many people do not fully understand this, and the example above is a graphic representing a built truck that the customer was unhappy with. Our situation is represented by 150 lbs. of weight for every inch the slide moves. Since sliding 5th wheels move in two-inch increments, there is a 300 lb. change at each location.
