At this year’s Heavy Duty Aftermarket Week (HDAW) trade show, Dana Holding Corp. has announced the launch of several key service parts that have been specifically designed for powertrains to optimize the benefits of engine downspeeding. More than 150 heavy-duty genuine Spicer part numbers have been added for the Spicer AdvanTEK 40 series tandem drive axles and Spicer Life Series SPL 350 driveshafts and universal joints.
“Spicer AdvanTEK axles and SPL 350 driveshafts have become the premier drivetrain offering for vehicle systems that take advantage of engine downspeeding,” said Doug Wolma, vice president and general manager, Dana Aftermarket Group. “Our service parts offering provides the same quality and performance features as our OEM parts for new vehicles. This is especially critical when considering the torsional load put on the drivetrain that is created by engine downspeeding.”
The new service items include genuine Spicer universal joints, axle carriers, axle housings, axle shafts, yokes, seals, overhaul kits, power dividers and more. All have been designed to effectively handle and manage the high torques and stresses on driveshafts, axles and inter-axle shafts associated with downspeeding, the company says.
Dana’s Spicer AdvanTEK 40 tandem axles are available in five ratios to support engine downspeeding, including what the company believes to be the industry’s fastest at 2.26:1. Weighing 21 pounds less than competitive 40,000-pound tandem assemblies, the axles also enable increased overall vehicle efficiency of 2 percent and can save more than 2,700 gallons of fuel over five years, reducing carbon-dioxide emissions by more than 60,000 pounds, according to Dana.
The SPL 350 driveshaft and SPL 250 inter-axle shaft are designed to withstand the increased stresses placed on the drivetrain by high-efficiency on-highway trucks configured for engine downspeeding. The driveshafts offer high-power density design features and extended bearing life.
As a system, AdvanTEK axles and SPL driveshafts are the only combination in the trucking industry that can supply up to 1 million miles of life expectancy in a powertrain designed for engine downspeeding.
