Peterbilt Medium Duty 337
Flexible Configurations
Versatility.
The Peterbilt Model 337 is built to take on the big jobs. That's why it's available as a Class 7 truck or tractor with a GVW up to 33,000 lbs. With a full range of suspensions and in an all-wheel-drive configuration, the 337 delivers an ideal match for applications such as wrecker, tanker, beverage delivery, municipal utilities – just about any job you can throw at it.
PACCAR PX Engines
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. 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.
Durability And Reliability
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.
INTERIORS
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.
