April 22, 2013 – Dana Holding Corp. has introduced the Spicer EconoTrek tandem axle, a new lightweight 6x2 configuration that improves performance, reduces maintenance, and increases fuel economy for heavy-duty line haul tractors.
The Spicer EconoTrek tandem axle is expected to improve fuel economy by up to 3 percent through decreases in mechanical drivetrain energy loss and reduces weight by up to 400 pounds when compared with a traditional 40,000-pound tandem axle arrangement.
Available this June, the Spicer EconoTrek tandem axle combines the company’s newly upgraded Spicer S170 and S190 single-reduction single drive axles with the lightweight Spicer S20-045B tag axle.
First introduced in 2004, Spicer S170 and S190 high-performance single drive axles have been outfitted on more than half a million commercial vehicles and are designed for efficiency while withstanding demanding applications. Now improved to ensure optimal operation and durability with less required maintenance, the Spicer S170 and S190 drive axles are even more resistant to abusive differential spin-out events.
The new Spicer S20-045B axle features advanced designs leveraged from Dana’s line of Spicer commercial-vehicle drive axles. Made of high-strength, micro-alloy steel with a thin-wall, square-edge formed axle housing box, the Spicer S20-045B axle is shaped like a low-profile drive axle to provide significant strength for the axle’s vertical load-bearing capabilities, reducing tire wear while simplifying suspension and chassis installation at a lower weight.
The Spicer EconoTrek tandem axle is optimized for use with electronic-controlled air suspension systems, such as the new Bendix eTrac system. The eTrac system will seamlessly transfer weight to the Spicer S170 or S190 series drive axle for improved low-speed traction when combined with the Spicer patented wheel-differential lock feature.
