Spicer EconoTrek Tandem Axle

Dana's Spicer EconoTrek tandem axle comes as a lightweight 6x2 configuration that improves performance, reduces maintenance and increases fuel economy for heavy duty line haul tractors. Its design decreases in mechanical drivetrain energy loss and reduces weight by up to 400 lbs when compared with a traditional 40,000-lb tandem axle arrangement. The tandem axle comes made of high-strength, micro-alloy steel with a thin-wall, square-edge formed axle housing box. This adds significant strength for the axle's vertical load-bearing capabilities, reducing tire wear while simplifying suspension and chassis installation at a lower weight.
