Navistar International

The register lists 6 versions of these chassis series here; the engine on record is rated at 242.4 kW (325 hp), the kind of unit fitted to the heavier school-bus and coach chassis in the DuraStar and 3000 series.

In the United States and Canada, International ranks among the leading suppliers of school-bus chassis, which body builders such as Blue Bird, Thomas Built Buses or Navistar's own IC Bus division turn into complete school buses; the DuraStar and 3000 series form the basis of the classic yellow school bus, while the MV Series represents the newer, more aerodynamic generation.

For a used example, check the chassis and axles for corrosion and wear, engine and gearbox condition, brake system operation and, depending on the given body builder's construction, the state of the floor, windows and door mechanisms; chassis parts run through the Navistar/International dealer network.
