Dana Holding Corporation has introduced the Spicer  AdvanTEK 40 tandem axle. This all-new 40,000-lb tandem axle for a variety of  Class 8 applications features a design that increases fuel economy, improves  reliability, reduces vehicle weight, and decreases total ownership costs.

  The Spicer AdvanTEK 40 axle is estimated to deliver more  than $8,000 in operating savings over a five-year period through a combination  of features including the industry’s fastest axle ratio of 2.26:1, lower axle  weight, optimum inter-axle driveline angles, and reduced lubrication quantity.

  This axle was developed with faster axle ratios to handle  higher input torques, lowering engine rpm at cruise speed while increasing axle  efficiency by up to 1.2%. The Spicer AdvanTEK 40 axle will be offered with  ratios ideally suited for direct-drive transmission drivetrains requiring rear  axle ratios from 2.26 to 2.79 and overdrive transmission drivetrain ratios from  2.93 to 3.91.

  The Spicer AdvanTEK 40 axle is up to 21 pounds lighter  than other 40,000-lb. tandem axles. It is available with additional options  such as Dana’s patented wheel differential locks, lubrication pump, breather,  and Spicer LMS and LMSi hubs. Other options include thick-wall housings and  Dana’s versatile SelecTTrac system for maximizing GAWR rating for aluminum hubs  and maximizing bearing life in single wide-based tire configurations.

  Optimum inter-axle driveline angles allow for parallel  axle installation, avoiding installation variables and vehicle issues with  certain air-ride suspensions. Further refinements in the design of the Spicer  AdvanTEK 40 axle deliver improved durability of U-joints, less vehicle  downtime, and lower maintenance costs.

  Dana will start production on the axle in early 2014.  Visit www. dana.com/commercialvehicle for more details.
