Shop New Sierra 3500 Models

At Heritage GMC Buick, we have a healthy selection of GMC trucks, including the Sierra 3500 HD in the trim and configuration to upgrade your every journey. You won't have a tough time finding your ideal setup on our lot.

You can add or remove features to meet your needs with optional packages and GMC accessories. Different trims provide specialized or upgraded amenities to ensure you get what you need. They're all built for power and purpose, but slightly skewed toward one functionality over others. The AT4X, for example, includes tough bumpers, rugged accents, and off-roading extras, excellent for use on unpaved surfaces and adventures off the beaten path, versus the Denali with its sophisticated exterior styling and luxury interior elements, and we've barely scratched the surface here.

The gorgeous interior features, luxurious materials, and matching styling for the dash complement the excellent technology underpinnings. A large touchscreen display rests right in the center, ready to play your favorite jams or keep you navigating efficiently on country back roads and highways alike. 

With lots of bed space, regardless of the size you choose, there's plenty of room to haul or store gear. You can load tons of lumber, building supplies, plants, rocks, tools, or all of the above. It's like having an entire trailer attached, but realistically, you could add a trailer, as well. The Sierra 3500 HD pulls no punches when it comes to stowing whatever you need. You'll never have to leave anything behind.

You'll know how it was cared for, if there were any notable events, how many drivers sat behind the wheel, and a few other details. They say never buy without that knowledge and it's all here.

Plus, the Sierra 3500 HD is a stunner front to back. It has a bold front end, multipurpose tailgate, remarkable safety features, and the towing capacity and advanced trailering amenities you need to keep you going for days.
