Kenworth now offers the new Dana Spicer EconoTrek 6x2 tandem axle for order with its new Class 8 on-highway trucks.
Key benefits of the Spicer EconoTrek lightweight drive and tag axle configuration include enhanced fuel economy, weight savings, improved performance, and reduced maintenance.
According to Dana, Spicer EconoTrek is up to 3% more fuel-efficient compared with traditional 6x4 tandem axles. It also is more than 300 pounds lighter than Kenworth’s standard 40,000-lb drive axle configuration. The drive and tag axles can accommodate both dual and wide-base tires and gear ratios range from 2.53 to 7.83.
EconoTrek features a robust housing design. It is optimized for use with electronic-controlled load distribution air suspension systems and must be specified with the Kenworth AG380 or AG400L suspensions. Operators also must spec a driver-controlled differential lock and the Bendix eTrac Traction Enhancement option, which transfers weight to the drive axle for better low-speed traction.
