Dana Holding Corp. now offers a Spicer SelecTTrac housing option on its Pro-40 tandem axle. The housing design optimizes the use of wide-based tires for customers wanting the flexibility to convert between wide-base single tires with low off-set wheels and standard dual wheels with a single housing.
“Wide-base single tires are becoming increasingly popular as the industry looks for ways to improve efficiency,” says Mark Wallace, president, Dana On-Highway Driveline Technologies. “With Spicer SelecTTrac, customers can benefit from the weight and fuel savings of wide-based single tires and still maximize their axle system weight rating and wheel-end life.”
Spicer SelecTTrac will be available on Dana’s Spicer Pro-40 tandem axle.
