The advanced DURAMAX diesel in the Sierra 2500HD delivers 397 hp and 765 lb-ft of torque, making it the most powerful Sierra ever. The DURAMAX Diesel engine has a strong reputation and a proven track record with nearly 1.4 million sold since 2000. Paired with the sophisticated Allison® 1000 Series Transmission with overdrive, this available powertrain also offers a maximum highway range of up to 680 miles on a single fill-up.
This ferritic nitrocarburizing technology is a GM-exclusive patented process that hardens and strengthens brakes. Duralife®12 protects against corrosion and can double the life of the brakes compared to conventional rotors.
The enhanced Allison 1000 is designed to handle the higher torque capability of the 6.6L DURAMAX engine, while also helping improve fuel economy and provide seamless assistance with the exhaust brake system.
