Kenworth is now accepting orders for Class 8 vehicles spec’d with the Dana Spicer AdvanTEK 40 tandem axle. The axle can be ordered on P&D, regional and linehaul trucks equipped with the Kenworth AG380 or AG400L suspension.

“The Spicer AdvanTEK 40 tandem axle is an excellent, fuel-efficient addition for new Kenworth Class 8 trucks,” said Kurt Swihart, Kenworth marketing director. “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.”

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

The axle was developed with some of the industry’s fastest ratios to handle higher torque and lower engine RPMs at cruise speed. Axle ratios of 2.26, 2.39, 2.53, 2.64 and 2.79 are available on Kenworth Class 8 trucks, including the T680 and T880. 

The AdvanTEK 40 includes a flow-through lubrication system for the inter-axle differential; a high-efficiency, on–demand lubrication pump; a “no-maintenance” U-tube breather. It also boasts wheel differential locks; “innovative” lube-flow enhancements; and the SelecTTrac solution for wide-based single-tire configurations.
