2004 Chevrolet W5500 Tiltmaster

The 2004 Chevrolet W5500 Tiltmaster is a medium-duty cab-over truck often used for delivery, construction, and service applications. Engine options for the 2004 model year included the 5.7L Vortec V8 gasoline engine and the 7.8L Isuzu 6HK1-TC diesel engine. The 5.7L gas engine produced approximately 290 horsepower and 330 lb-ft of torque. The Isuzu diesel engine, the more common choice, generated around 200-230 horsepower and 441-516 lb-ft of torque. Drivers appreciate the Tiltmaster for its maneuverability, tight turning radius, and ease of cab access.
