Dana this week introduced the Spicer S172 series single drive axle and Spicer D172 series heavy-duty tandem axle, each weighing 60 pounds less than their S170 and D170 predecessors.
The Spicer S172 axle has a rear ratio range from 3.07 to 6.14 and is suited for 4×2, 6×2, and 8×2 applications up to 25,000 pounds GAWR. The high-strength pinion bearings allow for greater lifespan under heavy loads, improving durability and overall performance.
The Spicer D172 tandem axle is suited for construction, heavy-haul and severe-service applications.
Both axles feature High-Power Density AdvanTEK gearing to maximize strength and reduce weight. In addition, both use a passive lube management system requires less lube while utilizing a patented meter to optimize the amount of lube flow to the high-efficiency bearings.
The axles will be available beginning in the second quarter of 2018.
