The Dana Spicer AdvanTEK 40 tandem-drive axle is now available for all Peterbilt heavy-duty truck models. The axle design with AdvanTEK gearing and optimized integration with Peterbilt’s chassis is said to improve fuel efficiency by up to 2 percent. The non-maintenance u-tube breather that extends lubricant life and less lubricant is required with an on-demand lubrication system that only pumps when necessary, reducing the needed amount by up to five pints.

Optimum inter-axle driveline angles minimize noise vibration harshness to increase u-joint life and reduce wear on other components. The axles also feature differential locking to provide maximum traction when needed.

The AdvanTEK 40 is available on Peterbilt Models 587, 579, 567, 389, 384, 382, 367, 365, 348 and 320. It is ideally suited for direct-drive transmission drivetrains requiring ratios from 2.26 to 2.79. It is also compatible with the SPL350-XL (required with and limited to 2.26 and 2.39 axle ratios) and SPL250-XL drivelines.
