Peterbilt makes available AdvanTEK 40 tandem axle

Oct. 3, 2014

Peterbilt Motors Co. is now offering the Dana Spicer AdvanTEK 40 tandem-drive axle as an option on its heavy-duty truck models.

The efficient axle design with AdvanTek gearing and optimized integration with Peterbilt’s chassis can improve fuel efficiency by up to 2.0%, or approximately $1,500 in fuel costs annually, the OEM said.

“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,” he continued.

The axle features a 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, Peterbilt stated.

Optimum inter-axle driveline angles minimize noise vibration harshness to increase u-joint life and reduce wear on other components, according to the company. 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. The OEM said the axle 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.
