Optimized Engine Performance

To maximize trailering capability and overall performance, the Sierra HD utilizes the Dual Path Air Induction System to optimize airflow and cooling of the 6.8L Duramax Turbo Diesel V8 engine. Combined with the massive 28” internal fan, and factory-default Diesel After-Run cooldown features, the Sierra HD is built to haul heavy loads over a long, durable lifespan.

Traction Select w/ Tow/Haul & Off-Road Modes

Utilize Traction Select to quickly switch between multiple traction configurations, including Off-Road mode and Tow/Haul mode, to optimize powertrain calibrations, traction control settings and stability control system calibrations for any driving condition you’re facing. Best of all, this feature remains defaulted up to 4 hours after the truck is turned off, so you don’t have to switch back and forth after brief stops along the way.
