Proven durability. Superior performance

The Heart of Peterbilt Medium Duty

Available with either the PACCAR PX-7 or the PACCAR PX-9, the 337 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 337, the PACCAR PX-7 is available in horsepower ratings from 200 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, vocational or specialty applications industry-leading quality, reliability and fuel economy.

Peterbilt craftsmanship

Enduring Dependability

The Model 337 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 Meet

The Model 337’s technology starts literally on the leading edge with high-intensity forward lighting. As soon as drivers sit behind the wheel, it will be obvious that this is one advanced truck. The LED backlit gauges readily communicate systems status and are designed to reduce eye strain. The standard driver’s in-dash display includes virtual gauges and truck, trip and performance information in driver-selectable English, French or Spanish. The optional diesel electric hybrid controls provide real-time feedback to the driver, encouraging optimal driving style and maximizing efficiency.
