Tough as Nails

Regardless of the work that needs to be done, a heavy-duty truck is required. The GMC Sierra HD and the Chevy Silverado HD excel in toughness thanks to the powerhouses under their respective hoods. Their durable engines give these trucks the strength needed to tow up to 36,000 pounds when properly equipped.

While the Sierra HD and the Silverado HD can tow the same equipment, the Sierra HD proves there's more to towing than numbers. The GMC Sierra HD offers ample trailering assistance technologies. This includes available features such as:

• In-Vehicle Trailering App
• Trailer Side Blind Zone Alert
• Up to 14 camera views for towing
• Trailering mirrors
• Adaptive Cruise Control with Trailering

While the Silverado HD also offers various trailer camera angles, its available Adaptive Cruise Control system lacks trailering capabilities.

Make Anywhere Your Office

Each day may bring a new work location, so your truck can sometimes act as a mobile office. Load up your tools and equipment for the day in the truck bed, toss in your cooler, and anything else you might need. When correctly configured, the Sierra HD and the Silverado HD each have a maximum cargo bed volume of 83.5 cubic feet.

A 6-way tailgate system is available with each truck, allowing you to configure the tailgate as a flat work surface or full-width step for easy access to the truck’s bed. An available MultiPro™ Audio System by Kicker turns the truck’s bed into the most popular tailgate destination. This tailgate audio system can stream music via Bluetooth® through the 2-channel exterior speaker system.

Additionally, a standard Wi-Fi® hotspot lets you check work emails from any job site, ensuring you’re always in the know of last-minute project adjustments.

Get Out & Explore

When the weekend rolls around, your GMC Sierra HD or Chevy Silverado HD transforms into a warrior ready to conquer whatever comes its way. That's especially true if you choose the GMC Sierra HD AT4 or AT4X trim level, specially designed to handle even the most unforgiving terrain.

Depending on which trim you choose, you’ll have access to these impressive off-roading capabilities:

• Up to 11.6 inches of ground clearance
• 1.5-inch factory-installed suspension lift
• Rear electronic-locking differential
• Steel skid plates
• Off-road suspension with Rancho® shocks

With these features, you'll feel confident trekking along unpaved roads and climbing rocky mountains with your GMC Sierra HD. Sadly, with only one off-roading trim, the same may not be said for the Chevy Silverado HD.

Room for the Weekend Crew

Everyone knows that weekends are better spent with friends. Whether loading up your fishing boat for a day on the water or taking your crew to the rink for a pick-up hockey game, the GMC Sierra HD and the Chevy Silverado HD offer ample seating to ensure no one misses out on the fun.

When comparing the Crew Cab configurations of these trucks, you’ll see that they share a few dimensions, including:

• Headroom (front/rear): 43.03/40.12 in.
• Legroom (front/rear): 44.53/43.4 in.
• Shoulder room (front/rear): 66.02/65.3 in.
• Hip room (front/rear): 61.18/60.24 in.

With shared dimensions, either the GMC Sierra HD or the Chevy Silverado HD offers the space needed for your whole crew.

Even though the GMC is a heavy-duty truck, riders will feel like they’re traveling in a luxury model, thanks to available premium touches like exclusive Alpine Umber interior and Paldao wood. The Chevy may have similar features, but it lacks the upscale touches found with the ultra-luxurious GMC Sierra HD Denali Ultimate trim.

A Comfortable Commute Awaits

Thanks to the ample passenger-focused features inside these trucks, your family will love climbing into the cab of your GMC Sierra HD or your Chevy Silverado HD. Standard wireless Apple CarPlay® and Android Auto™ make it easy to entertain on the go.

Once paired, your smartphone is mirrored onto your truck's central touchscreen display. From there, you can access compatible digital features, including your family’s playlist of favorite songs, so you never have to touch your phone while behind the wheel.

Both trucks offer available dual-zone automatic climate control, heated front and rear seats, and ventilated front seats. However, only the GMC Sierra HD takes comfort to new heights with its optional 16-way power front seats with massaging capability. This feature will help relieve lingering back and shoulder tension for you and your partner, proving that the GMC Sierra HD is better suited for family comfort.

Superior Safety Comes Standard

The safe arrival of your loved ones is the most important thing. The engineers at GMC and Chevy understand this, so both trucks have advanced monitoring tech that works with your defensive driving skills to help prevent a collision. Regardless of which truck you choose, you’ll have standard and optional access to features like:

• Front Pedestrian Braking
• Automatic Emergency Braking
• Lane Change Alert with Side Blind Zone Alert
• Following Distance Indicator

These features provide enhanced peace of mind while you’re behind the wheel. Still, there’s one extra feature of the GMC Sierra HD that provides added protection: Trailer Side Blind Zone Alert. This available system helps you more confidently change lanes with a trailer attached to your truck with alerts that indicate a hard-to-see vehicle. The Chevy Silverado HD also has this feature, but while it’s largely available with the GMC, it’s exclusive to just the top trim of the Chevy.
