DMAX is home to the Duramax 6.6L Turbo Diesel engine used in the Chevrolet Silverado and GMC Sierra. The current Duramax is SAE certified at 397 horsepower (296 kW) at 3,000 rpm and 765 lb-ft of torque (1,037 Nm) at 1,600 rpm.

All Duramax engines include a high-pressure (30,000 psi/2,000 bar) Piezo-actuated fuel system for greater fuel efficiency, improved performance and reduced emissions. The Duramax is also available in the Chevrolet Express and GMC Savana full-size vans.

"It has been the successful partnership among GM, Isuzu and IUE-CWA Local 755 that continues to bring new investment dollars to our plant," said Shinichi Suzuki, President, CEO and chief operating officer for DMAX.
