Peterbilt 348

Flexible Configurations


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.


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.

The 8.9-liter PACCAR PX-9 Engine has one of the highest power-to-weight ratios in its class (260-380hp), with heavy-duty features like replaceable wet liners, roller cam followers, bypass oil filtration and targeted piston-cooling. Available in both medium- and heavy-duty configurations, PACCAR PX Engine options give customers in traditional Class 7, Class 8, vocational or specialty applications outstanding fuel economy, greater reliability and unsurpassed performance.

Durability and Reliability

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.


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.
