The Dana Spicer AdvanTEK 40 tandem drive axle is now available on Peterbilt's model 348 medium-duty and 320 vocational trucks.
The efficient axle design with AdvanTEK gearing and optimized integration with Peterbilt’s chassis can improve fuel efficiency by up to two percent, or approximately $1,500 in fuel costs annually, according to the company.
Customers can realize additional savings through lower service requirements and reduced downtime. For instance, it features the industry’s first 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. Durability and reliability are enhanced through the AdvanTEK 40 design. 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 also available on Peterbilt heavy-duty Models 587, 579, 567, 389, 384, 382, 367, and 365.
