Kenworth’s K270 and K370 medium-duty cabovers will now be available with three Dana Spicer axle series for different applications.

The Kenworth cabovers can be spec'ed with the Dana Spicer S140 series of single-reduction, single-drive axles, ranging from 16,000- to 21,000-pound gross axle weight rating.

The two S140 series axles are designed to handle a wide range of applications and feature broad ratio coverage from 3.31 to 6.50. The axles feature high-capacity gearing and bearing systems designed to improve durability and reliability with higher horsepower and torque engines. Standard “R” series spindles are used for ease of fit up and commonality.

The S140 axle design also features GenTech gearing that can reduce noise levels by up to 12 decibels compared to standard gear designs and provide a smoother vehicle ride. The S140 series axles offer a weight savings of up to 85 pounds compared to the Dana P20060S axle.

The Dana Spicer S21-172 and S21-172E single-reduction, single-drive axles offer better durability, reliability, and efficiency than the S170 series, according to Dana.

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

The 10.000-pound rated Dana Spicer E1002IL steer axle features a steel-forged beam design to reduce weight and improve strength and torsional stiffness for improved braking response. It is available in both standard and wide beam widths.

The axle features a, one-piece forged design, which includes the steer arm, tie rod arm, and spindle for turn angles up to 55 degrees. There also is a large diameter kingpin with 15% larger bushing area, kingpin joint-sealed thrust bearings with compressible inserts for improved strength, and standard and wide beam widths to increase maneuverability.
