Kenworth says it has added Dana’s Spicer AdvanTek 40 tandem axle for new Class 8 pickup & delivery, regional haul and linehaul trucks equipped with the Kenworth AG380 or AG400L suspension. 

“The AdvanTEK 40 axle is featured as a key part of the special Kenworth T680 Advantage configuration designed to help Kenworth customers maximize fuel efficiency,” said Kurt Swihart, Kenworth marketing director. 

The Spicer AdvanTEK 40 axle incorporates a special gearing design which can help increase fuel economy, improve reliability, reduce vehicle weight, and decrease total ownership costs, according to Dana. 

The axle has some of the industry’s fastest axle ratios to handle higher torque and lower engine RPM at cruise speed. Axle ratios of 2.26, 2.39, 2.53, 2.64 and 2.79 are available on Kenworth tractors and trucks, including the T680 and T880. 

Patented technologies offered on the AdvanTEK 40 include a flow-through lubrication system for the inter-axle differential; high-efficiency, on–demand lubrication pump; no-maintenance U-tube breather; differential locks; lube flow enhancements; and the SelecTTrac design for wide-based single-tire configurations.
