The Kenworth T270 and T370 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 four 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 excellent durability and reliability with higher horsepower and torque engines due to high-capacity gearing and bearing systems, Dana said. Standard “R” series spindles are used for ease of fit and commonality, and GenTech extra-quiet gearing can reduce noise levels by up to 12 decibels versus standard gear designs.
