Peterbilt provides updates to Model 320

Peterbilt Motors Company introduces a range of new features for the popular Model 320, providing customers improved maneuverability, increased vehicle utility and enhanced driver comfort. Renowned for maneuvering large payloads in confined spaces as well as availability of alternative fueled hydraulic hybrid powertrains, the Model 320 is ideally suited for a variety of vocational markets including refuse, construction, tanker and fire service applications.  

“Peterbilt’s low cab forward vehicle, the Model 320, is known for standing up to the harsh demands of the refuse and vocational industries with its uncompromising performance,” said Bill Jackson, Peterbilt general manager and PACCAR vice president. “And with its new features offering added flexibility, increased efficiency and an optimal work environment, the Model 320 is the ideal truck for this challenging market.”

New options for the Model 320 include:


The Model 320 is available with the two new steering gear options for enhancing maneuverability. The Sheppard HD94 offers front axle ratings up to 12,000 pounds, and the Sheppard SD110 offers front axle ratings up to 20,000 pounds. Both steering gear options offer ten percent wheel cut improvement, decreased turning radius and enhanced serviceability. The Sheppard SD110 is available in several configurations for added flexibility: a single gear rated up to 14, 600 pounds, a single gear with assist rated up to 20,000 pounds, or as a dual gear for either a left or right hand rated up to 20,000 pounds.


Utilizing the same frame space as a traditional battery box, the new light-weight aluminum, fender mounted battery box combines up to three batteries, a mount optional battery jumper posts and a disconnect all into one location. By configuring these components together, the Model 320 can be configured to save between 4 inches to 18 inches of linear frame space allowing for a shorter wheelbase which provides weight savings.  The battery box can also be installed on either side of the truck, simplifying body installation. This is beneficial to customers ordering the Hydraulic Launch Assist system, installing an automated side loader or installing a residential front loader body.


For optimal comfort and ride performance, Peterbilt is now offering new amenities including an armrest, headrest and additional lumbar support to the already favorable Sears C-2 air suspension seats which already delivers 5.25 inch suspension travel and ergonomic contoured molded cushions. The new features are available on both the driver and passenger seats.


To enhance visibility and safety, Peterbilt’s new tri-plane mirrors contain convex mirrors on the upper and lower planes with a remote controlled flat mirror on the middle plane. All three surfaces are heated, and feature an arm system that allows the mirror to be folded either forward or backward. And for added flexibility, the mirrors can be either traditionally mounted on the driver and passenger doors, or for a wider view range, the passenger side mirror can be innovatively installed to the front of the cab.
