Variable Valve Timing (VVT)
Direct Injection

The engine specifications include:

  • A displacement of 403.5 cubic inches (6,599 cubic centimeters)

  • 460 to 910 lb-ft (624 to 1,234 Nm) of torque at 1,600 to 4,200 rpm

The Chevrolet Duramax debuted in 2001 and has since become a powerhouse in the heavy-duty truck market. Known for its reliability, power, and efficiency, the Duramax has been continuously improved and refined over the years to meet ever-changing regulations and customer demands. It is the choice for many drivers who tow heavy loads, and the engine has been instrumental in the success of the Chevrolet Silverado and GMC Sierra trucks.

The Chevrolet Duramax is used in various Chevrolet and GMC applications, including the Silverado HD, Sierra HD, Express, and Savana. It is also used in the Chevrolet Kodiak, GMC TopKick, and some Navistar International trucks.
