The Spicer S172 series single drive axle for Class 7 and 8 vehicles, available from Dana, retains the robustness and strength of the existing S170 single drive axle, but weighs more than 60 pounds less. The axle is available in 4x2, 6x2, and 8x2 configuration up to 25,000 lbs GAWR. It offers a broad range of gear ratios, from 3.07 to 6.14, and features a low hypoid offset with High-Power Density AdvanTEK gearing to drive maximum efficiency. The high-strength pinion bearings allow for greater lifespan under heavy loads, improving durability and overall performance. 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.
