The Model 337 is built to take on the big jobs. That's why it's available only as a Class 7 truck or tractor with a GVW up to 33,000 pounds. It can be configured to meet the demands of virtually any work application and spec'd to meet the needs of any owner.

The Model 337 earned its durable reputation from features such as the Metton hood and stainless steel grille for superior protection of the cooling system. Plus, the sloping aerodynamic hood enhances driver visibility and productivity.
