The Dana Spicer AdvanTEK 40 tandem drive axle is now available for all Peterbilt heavy-duty truck models, Peterbilt Motors Co. recently announced.
According to Peterbilt, AdvanTEK’s gearing and integration with Peterbilt’s chassis can improve fuel efficiency by up to 2%, or approximately $1,500 in fuel costs annually.
“This new axle provides customers with numerous bottom-line benefits, particularly in linehaul applications, including higher fuel economy, lower maintenance and increased payloads,” said Robert Woodall, Peterbilt director of sales and marketing. “With the AdvanTEK 40 customers can spec the fastest axle ratios in the industry to handle higher torque input while reducing engine speeds by 200 rpm for better fuel efficiency.”
Peterbilt notes that the Spicer Advantek 40 tandem axle features the industry’s first non-maintenance u-tube breather that extends lubricant life. As a result, less lubricant is required with an on-demand lubrication system that only pumps when necessary, reducing the needed amount by up to five pints.
Additionally, 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.
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 compatible with the SPL350-XL (required with and limited to 2.26 and 2.39 axle ratios) and SPL250-XL drivelines.
