MAUMEE, Ohio, March 6, 2013 /PRNewswire/ -- Dana Holding Corporation (NYSE: DAN) announced today that the Spicer® Pro-40™ tandem axle is now offered in the 2013 PACCAR data books for commercial vehicles under the Kenworth and Peterbilt nameplates. Featured at the Technology & Maintenance Council's 2013 Annual Meeting and the Mid-America Trucking Show this month, the Spicer Pro-40 family of heavy-duty 40,000-pound tandem drive axles supplies a reliable, lightweight option for linehaul, bulk, regional, and city delivery fleets. It offers a dramatic weight reduction and improved power density, enabling customers to increase payload, improve fuel economy, and ultimately improve their bottom line. The axle is nearly 100 pounds lighter than the nearest competitive axle, and now offers a new thinner wall version for further weight reductions on select applications. Available in a wide range of ratios from 3.25 to 3.90, the Spicer Pro-40 axle is ideal for commercial trucks with nine-, 10-, 12-, or 13-speed overdrive transmissions; diesel engines rated up to 475 horsepower and 1750 lb-ft. of torque; and gross combination weight ratings up to 80,000 lbs. "Most of our competitors offer a single 40,000-pound tandem product that is designed to meet a broad spectrum of application requirements, but it is clear that one size is not the optimum solution for all," said Pat D'Eramo, president of Dana Commercial Vehicle Driveline Technologies. "The Spicer Pro-40 axle offers a dramatic weight reduction because it allows customers to spec exactly what they need to maximize efficiency." The Spicer Pro-40 axle has been available to PACCAR customers by specific request since 2012. Popular among refrigerated fleets, bulk haulers, flat bed fleets, fuel haulers, and dry van fleets, the Spicer Pro-40 axle joins a long list of advanced drivetrain products available through PACCAR data books, including Spicer® steer and drive axles, driveshafts, tire-management solutions, and low-maintenance wheel end offerings.
