Dana Holding Corp. has launched the Spicer S140 series, a new family of single-drive axles specifically engineered to improve fuel economy, reduce maintenance costs, increase operator comfort, and boost overall vehicle performance on medium-duty trucks.

Now available, the new Spicer S140 series single-reduction axles replace all previous 17,000- to 19,000-lb Spicer drive axles. They are available for all makes and models of straight truck chassis up to 19,000-lb gross axle weight ratings (GAWR), including delivery vehicles; school buses; shuttle buses; and rescue, municipal, and utility vehicles.

“Throughout the development of the Spicer S140 Series, we focused our efforts on helping medium-duty fleet managers optimize the productivity of their fleets,” said Steve Slesinski, director of product management for the Dana Commercial Vehicle Systems Group. “With this new series, Dana enhances its reputation as the leader in delivering advanced drive axle technology and superior value for the medium-duty market.”

Spicer S140 Series axles are 85 lbs lighter, compared with previous Dana and current competitive medium-duty axles, helping to improve fuel economy. The manufacturer said that with an initial Roadranger lubrication drain at 250,000 miles and 32% less lubrication required overall, these axles are easier to maintain and more environmentally friendly than previous Dana and current competitive designs.

Spicer S140 Series axles offer 23 more millimeters of ground clearance while improving NVH performance by nearly 240% over other axles with the same GAWR, said Dana. Additionally, Spicer S140 Series axles are assembled in the U.S. and meet NAFTA regulations for content.

Dana said the new axles are optimized to perform in vehicles with drivetrain ratings up to 860 lb-ft of torque and up to 300 horsepower, and support gross combination weight ratings up to 46,000 lbs and typical Gross Vehicle Weight Ratings up to 31,000 lbs in most vocational applications. Maximum Gross Combined Weight Ratings of 50,000 lbs and Gross Vehicle Weight Ratings of 33,000 lbss are available under specific application approvals.

Spicer S140 Series axles are also available with a number of options for prime operation, including a carrier-integrated parking brake or electromagnetic retarder mount; a wide-track design for maximum stability; a patented axle breather design supplying unrestricted air flow and minimizing the risk of seal leaks due to axle pressurization; and integral, welded suspension brackets for increased strength and durability.
