The standard 6.6L V8 gas engine delivers dependable strength for everyday tasks. For maximum performance, the available Duramax 6.6L Turbo-Diesel V8 produces up to 470 horsepower and an impressive 970 lb-ft of torque.

Both engines pair with a 10-speed Allison automatic transmission, which provides smooth gear transitions and optimal performance under load. Whether you're hauling large trailers or carrying heavy payloads, this powertrain delivers consistent and reliable performance on the job site or highway.
