Peterbilt Medium Duty 348
Versatility
The Model 348 was designed to exceed the rigid demands of Class 7 and Class 8 specialty application markets that require rugged durability and a wide range of optional content. The Model 348 represents a multi-dimensional performer with a GVW from 33,000 to 66,000 lbs. and optional capacity ratings to suit almost any vocation. The 348 is also available in a specifically designed all-wheel-drive configuration. From construction and crane service to utility and delivery services in both Class 7 and Class 8 markets, the 348 is in a class by itself.
Proven Durability. Superior Performance.
The heart of Peterbilt medium duty
Available with either the PACCAR PX-7 or the PACCAR PX-9, the 348 has the power to get the job done. The 6.7-liter PACCAR PX-7 Engine delivers superior performance, minimizes operational costs and maximizes uptime for medium-duty customers. Reduced maintenance, long service intervals and excellent fuel efficiency add up to a superior lifetime value. On the 348, the PACCAR PX-7 is available in horsepower ratings from 280 to 360hp and offers up to 800 lb-ft of torque.
Spec'D For The Job
Heavy duty vocational options.
The Model 348 is constructed with an all-aluminum cab that is lightweight for fuel efficiency and corrosion-resistant for durability. The Metton® hood is lightweight but strong, and tilts open a full 90 degrees for easier access to key service points. The stainless steel grille surround is long lasting, and its durable design provides superior protection of the engine cooling system.
INTERIORS
Where form and function work.
The ergonomic dash features LED backlit gauges that are easy to read, a driver information display for critical vehicle data and rocker switches within easy reach. Power controls for door locks and power windows are conveniently located in the door panel, and a multi-functional turnstalk and easy-to-read driver information center provide a comfortable, ergonomic driver environment. An in-mold process embeds color directly onto the dash for a long-lasting finish, virtually eliminating fading, scratching and peeling.
