Dana Holding Corp. has launched a new Spicer Life Series main driveshaft and inter-axle shaft specifically designed to supply greater torque in severe-duty vocational applications as well as low-emission trucks. The latest in an upgraded line of Spicer heavy-duty universal joints, Dana will be offering standard service and extra heavy-duty versions of the SPL-350 driveshaft, as well as the complementary SPL-250 inter-axle shaft, in the second half of 2013.
The new heavy-duty U-joints, according to Dana, eliminate application restrictions on engine power in Class 8 linehaul and vocational vehicles. “As vehicle manufacturers downspeed engines, torque demands on the rest of the drivetrain increase dramatically,” said Pat D’Eramo, president of Dana Commercial Vehicle Driveline Technologies. “These new driveshafts have been designed to provide the durability, size, and weight needed.”
