Kenworth has added the availability of three Dana Spicer axle series for its K270 and K370 medium duty cabovers. Kenworth’s cabovers are now available with the Dana Spicer S140, E1002IL, S21-172 and S21-172E axles.

The Dana Spicer S140 series of single-reduction, single-drive axles, pictured above, range from 16,000- to 21,000-lb. gross axle weight rating and, according to Dana, are designed to handle a wide range of applications and feature ratio coverage from 3.31 to 6.50. The S140 axle design also features GenTech extra-quiet gearing to reduce noise levels by up to 12dB versus standard gear designs and provide a smoother vehicle ride. The S140 series axles offer a weight savings of up to 85 lbs. compared to the Dana P20060S axle.

The Dana Spicer S21-172 and S21-172E single-reduction, single-drive axles have a 21,000-lb. rating and are available in ratios between 3.07 and 6.14. The S21-172 offers reductions of 57 lbs. in weight, 10 pints in oil usage, and 10 to 20% in power loss for the same ratio compared to its predecessor S21-170, Dana says. The S21-172E has the same weight and oil usage as its S21-170E predecessor.

The 10-000-lb. rated Dana Spicer E1002IL steer axle features a steel-forged beam design, which reduces weight and enhances strength and torsional stiffness for improved braking response. According to Dana, the axle offers up to a 35-lb. weight reduction per vehicle for increased payload and productivity.
