Dana Holding Corp. has launched the Spicer S140 Series, a new family of single-drive, medium-duty axles specifically engineered to improve fuel economy, reduce maintenance costs, increase operator comfort and boost overall vehicle performance, the company said.
Now available on International brand 4300, 4400, 7300 and 7400 vehicle platforms, the new Spicer S140 Series single reduction axle was specifically developed for medium-duty vehicles. The new family of axles is available for straight truck chassis up to 19,000 lbs. gross axle weight ratings (GAWR), including delivery vehicles; school buses; mini buses; shuttle buses; motor homes; and rescue, municipal and utility vehicles. In mid-2010, the S-140 will also be the standard Class-6 axle at another major OEM.
“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 nearly 100 lbs. lighter compared with current competitive medium-duty axles and 85 lbs. lighter than the current Spicer axle, helping to improve fuel economy and offset vehicle weight increases due to new emission systems. 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, according to the company.
Spicer S140 Series axles offer 23 mm more ground clearance while improving NVH performance by nearly 240% over other axles with the same GAWR, the company said.
Optimized to perform in vehicles with drivetrain ratings up to 860 lb.-ft. of torque and up to 300 HP, Spicer S140 Series axles 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.
