Dana Holding Corp.’s SPL 350 driveshaft and SPL 250 inter-axle shaft are designed to withstand the increased stress placed on the driveline by high-efficiency; on-highway trucks with downsped engines, as well as severe vocational applications including heavy equipment, mining, oil fields and road trains.
Delivering up to 35,000 Nm (26,000 ft.-lbs.) of torque capacity, the SPL 350 driveshaft and SPL 250 inter-axle shaft are equipped with high-power density design features that extend product life and outperform competing driveshafts. They offer more power density, 40% more torque carrying capability, and double the bearing life. Like all Spicer heavy-duty SPL U-joints, these products feature an optional service-free design for further maintenance and lifecycle benefits.
These Spicer Life Series products were specifically engineered for use with the Spicer AdvanTEK 40 tandem axle, which incorporates a powerful combination of technologies that can enable an engine at highway cruise speed to run up to 200 RPM lower than alternative powertrain systems while still reducing weight and increasing axle efficiency.
Dana has begun initial production of the Spicer AdvanTEK 40 tandem axle with a select number of popular axle ratios, including the industry’s fastest axle ratio of 2.26:1. The product’s full selection of 13 ratios from 2.26 to 3.91 and options for a variety of Class 8 applications will be available this summer.
