Kenworth K270 and K370 medium-duty cabovers now are available with three series of Dana Spicer axles.
The Dana Spicer S140 series of single-reduction, single-drive axles have a gross axle weight rating ranging from 16,000 to 21,000 pounds. They’re 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 S140 axle design also features GenTech extra-quiet gearing to reduce noise levels by up to 12 decibels versus standard gear designs and provide a smoother vehicle ride.
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 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.
