2023 GMC Sierra HD

2023 Sierra HD at Harry Brown's

To get the highest quality and most reliable heavy-duty truck at the fairest and most reasonable price, truck buyers know that Harry Brown's is the place to go for a new 2023 GMC Sierra HD. With five trim packages to choose from, there is a Sierra HD for everyone that offers more features and safety than the competition. In addition, you can add a few extra luxuries or tech features to make each drive more enjoyable.

True Heavy-Duty Capability

The Sierra HD 2500 and 3500 offer both gasoline and diesel in the 6.6-liter V-8 engine. The diesel power plant wins the horsepower comparison with 445, while the gas engine delivers a still very impressive 401. An Allison 10-speed automatic transmission is in the diesel models, while a 6-speed automatic transmission accompanies the gas engine. When evaluating the top-end towing capacity on the 2500, buyers love the 24,000-pound top end with another 3,862 in the payload. The diesel number is a bit higher at 27,500 towing, and cargo capacity is very comparable at 3,597 pounds. The 3500 Sierra HD numbers include a towing capacity of 24,000 pounds and a payload of 6,374 in the gas truck. And the biggest bang for your buck is the massive diesel that can handle 40,000 pounds on a trailer and 5,662 pounds of cargo in the bed.

Classic HD Truck Style

The Sierra HD is ready to take on challenging terrain off-road and any weather conditions and look great doing it. The impressive grille and scooped hood move all the air needed to keep the massive engines cool and performing at their peak. Nothing looks better with a scooped hood than sleek lines with a few robust curves and chrome accents. Even from the rear, the Sierra HD looks stylish with the six-position tailgate that converts from load step to work surface and variable location load stops.

Safety Technology & So Much More

The GMC Sierra HD lineup focuses on taking care of the driver and all passengers with cutting-edge technology. From 15 camera angles and a Head-Up Display to customer trailering settings and loads of driver-assist features, you have never been safer in an HD truck. And you are always connected to keep up on traffic and weather information or take a call on your Bluetooth-connected phone. Passengers in your Sierra HD will also enjoy access to Amazon Alexa, Apple CarPlay, and Android Auto.

Functional Truck Luxury

Inside the Sierra HD cabin, the driver and passengers enjoy luxurious features like climate-controlled and power-adjustable seating adorned in supple leather. The steering wheel is also offered in leather with a heat feature for those cold days when you need a little extra comfort. Finally, for those not driving or riding shotgun, the rear seating offers ample legroom, a folding center console, and excellent gear storage without taking up valuable seating space. Other top-end options include a wireless charging pad, Bose premium sound system, and Dual-Zone Climate Control.
