Dana's Spicer Pro-40 tandem axle is now offered in the 2013 Paccar data books for commercial vehicles under the Kenworth and Peterbilt nameplates.

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, according to Dana.

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 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 pounds-feet of torque; and gross combination weight ratings up to 80,000 pounds.

“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. Dana says it's popular among refrigerated fleets, bulk haulers, flatbed fleets, fuel haulers and dry van fleets.
