KALAMAZOO, Mich. — In a demonstration of its ongoing commitment to meeting new and future customer needs, Dana Corporation recently introduced the technologically advanced Dana Spicer S170 series of single-reduction, single-drive, heavy-duty axles.

Similar to the S190, which was introduced in 2003, the new Dana Spicer S170 series features the industry’s broadest axle ratio coverage, as well as high-capacity gearing and bearing systems to meet the requirements of higher horsepower and torque engines used in an increasing number of rugged and demanding applications. The axles are designed to perform in future vehicles with drivetrain ratings of up to 2,450 ft. lbs. of torque and up to 700 horsepower.

As a benefit of Dana’s integral component design processes, the S170 family of axles requires fewer than half of the components than competitive product offerings, providing increased robustness without the extra weight.

"For the fleet owner or driver, this means improved performance, lower maintenance, and more quality time on the road," said Patxi Garcia, product manager drive axle systems for Dana’s Commercial Vehicle Systems. "These new axles also offer additional weight savings through our use of High Power Density (HPD) technology. Some models are more than 25 pounds lighter than competitive models in the same class."

The S170 drive axle series features extra wide face-width gearing and a new hypoid gear design to provide extra strength, added durability, and quieter, more dependable operation. For maximum flexible specing options, the S21-170 (gross axle weight rating of 21,000 lbs.) and S23-170 (GAWR of 23,000 lbs.) models offer a ratio range of 2.69 to 7.17 lbs. The S25-170 (GAWR of 25,000 lbs.) model has a ratio offering of 3.31 to 7.17 lbs.

Available optional upgrades for the Dana Spicer S170 series, include:Driver-controlled, full-locking wheel differential to maximize traction; Dana Spicer LMS Low Maintenance Hubs to reduce maintenance; Wide-track axles for maximum stability; Welded suspension brackets for increased strength and durability; Axle mounted electro-magnetic retarders for more drivetrain options; ABS-ready axles

Dana Spicer S170 features include patent-pending axial power ribs, an integral pinion cage and carrier, induction hardened bearing journals, large wheel differential gearing, and precision forged differential gears. These features contribute to added strength, improved vehicle performance and longevity, as well as reduced life cycle costs.
