Powertrain & Performance

Choose between two engines when outfitting your 2021 Chevy Silverado HD. The Duramax® 6.6-liter Turbo-Diesel V8 sports a GM-exclusive air induction system and pairs with an Allison® 10-speed automatic transmission for smooth shifting across a wide range of gears. It generates 445 horsepower and 910 pound-feet of torque for supreme pulling power.

A 6.6-liter V8 gas engine utilizes technologies like Direct Injection and Variable Valve Timing to help it achieve 401 horsepower and 464 lb-ft of torque. A six-speed automatic harnesses that force for a comfortable, powerful ride.


Tow up to 36,000 pounds in a 2021 Silverado 3500 HD Regular Cab Long Bed 2WD when running off the power of the Duramax® Turbo-Diesel and equipped with the Max Trailering Package and gooseneck hitch. The 6.6-liter V8 gas can tow up to 17,370 pounds.

The 2021 Chevy Silverado 3500 HD can haul a payload of 4,572 pounds, making anything a possibility for the jobsite or the next family camping trip. The 2500 HD can haul up to 3,900 pounds, more than enough for a world-class fishing trip or tailgate party. Integrated bed steps help you load and unload the Durabed®, which offers more cargo volume than any competitor.


Towing massive weight has never been safer thanks to the 2021 Chevy Silverado HD’s class-leading 15 available camera views, which give you clear vision while backing up, parking, working through tight spaces, and hauling on the open road. An available multi-color 15 inch Head Up Display projects speed, navigation, and more above the steering wheel.

Apple CarPlay® and Android Auto™ connect your smartphone to your 2021 Silverado HD so you can have easy control over your favorite apps and features. Turn your heavy-duty truck into a mobile Internet provider with the available 4G LTE Wi-Fi® Hotspot, which can connect to devices up to 50 feet away.


An abundance of available safety features give you and your family the peace of mind you deserve whether you’re on a weeklong adventure or commuting in and around Sour Lake, TX. Rear Cross-Traffic Alert monitors for traffic coming from either side while you drive in Reverse, giving you eyesight where you didn’t have it before.

Front and Rear Park Assist help prevent low-speed collisions with small objects while parking. Lane Change Alert with Side Blind Zone Alert provides a side-mirror warning when a vehicle enters your blind spot on either side. Forward Collision Alert warns you if it detects a potential upcoming front-end collision, or if you begin to follow a vehicle too closely.

Lane Departure Warning helps you stay safely in your lane. Automatic Emergency Braking applies the brakes or helps you do so in the case of a potential front-end collision. Intellibeam® headlamps toggle between your regular lights and your brights based on traffic. Safety Alert Seats vibrate on the corresponding side of a potential collision for quick reaction times.


Best-in-class front head- and legroom gives you the space you need after a day of hard work. Available segment-first rear in-seatback storage compartments and 24-liter storage compartments that go under the rear seat help your Silverado HD stay roomy and clutter-free.
