Chevrolet & GMC Series

General Motors’ 2009 medium-duty lineup includes the Chevrolet Kodiak and GMC TopKick series, in addition to the T-Series and W-Series offered in both makes.

The Kodiak and GMC Topkick’s C4500 and C5500 continue to provide commercial customers a large selection of wheelbases, Regular or Crew Cab, and gasoline or diesel engines. Allison 6-speed transmissions are standard for all models.

The C6500/C7500/C8500 trucks remain the workhorses of the lineup, with up to 63,000 lb. GVWR. Regular Cab, Crew Cab (with room for up to six occupants) and Chassis Cab configurations are available.

On both makes, the T-Series’ cab-forward design offers the ruggedness of a medium-duty truck with visibility, maneuverability, and engine service access.

GM’s most notable updates for the 2009 medium-duty lineup are featured on the W-Series. The 2009 W-Series delivers Clean Idle certification for W4500, W5500, and W5500 HD models, with greater comfort and convenience, enhanced safety, and up-front bolder styling.

All 2009 W4500, W5500, and W5500 HD models are 50-state emission-certified and may idle for more than five minutes without having to shut down.

For improved appearance and durability, the 2009 Chevrolet W-Series is equipped with new seat stain-resistant seat covers.

Additional W-Series product improvements for 2009 include a factory-installed limited-slip differential for safer operation in severe weather, front suspension modifications for improved ride quality and driver comfort, improved speed-limiting calibration and additional programmable features for the power take off (PTO) operation, a vertical exhaust that resolves body mounting issues in applications where a horizontal diesel particulate filter is not advisable, and a chrome grille.
