Single-Reduction Drive Axles

Posted: April 14, 2015

Dana single-reduction drive axleFrom Dana comes a new family of single-reduction drive axles that leverages its AdvanTEK technology, a common head-assembly architecture, and other proven Spicer axle technologies to reduce weight, improve efficiency, and enhance durability.

Engineered for 6×2 and 4×2 configurations, these axles are said to be lighter than competing axles and feature a wide selection of ratios from 2.05:1 to 7.17:1, including fast, direct-drive ratios that support engine downspeeding. Not available until 2016, this new family of single-reduction drive axles is targeted at class 7 and 8 applications with a 21,000- to 26,000-lb axle-weight rating and an 80,000- to 100,000-lb gross vehicle weight.

Axles with AdvanTEK technology are said to be designed with increased power density and efficiency in a smaller package; smooth interior surfaces that decrease churning losses; superior machining and castings for extended durability; and an efficient lubrication system that requires 10% less lube.
