Model 337 -Medium-Duty Trucks
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.
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
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.
