Kenworth MD cabovers add Dana Spicer axle series

Kenworth has added the availability of three Dana Spicer axle series for its K270 and K370 medium-duty cabovers, according to an announcement.

The Kenworth cabovers are now available with the Dana Spicer S140 series of single-reduction, single-drive axles, ranging from 16,000 lb. to 21,000 lb. gross axle weight rating. According to Dana, 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, allowing maximum performance across a variety of vocations. The axles provide durability and reliability with higher horsepower and torque engines due to high-capacity gearing and bearing systems. Standard “R” series spindles are used for ease of fit up and commonality.

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 lb. compared to the Dana P20060S axle.

The Dana Spicer S21-172 and S21-172E single-reduction, single-drive axles provide increased durability, reliability and efficiency compared to the S170 series. 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 percent 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 lightweight, 10-000-pound 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. Available in both standard and wide beam widths, the axle offers up to a 35-pound weight reduction per vehicle for increased payload and productivity.

The axle features an exclusive, 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 percent larger bushing area for greater durability and reduced maintenance, kingpin joint-sealed thrust bearings with compressible inserts for superior strength, and standard and wide beam widths for enhanced maneuverability.
