New 2026 GMC Sierra 3500HD

The 2026 GMC Sierra 3500HD SLT Crew Cab 4WD in Summit White is built around a serious heavy-duty configuration: dual rear wheels, an 8.2-foot box, and the 6.6L Duramax turbo-diesel. This particular truck also has the Gooseneck/5th Wheel Prep Package and Snow Plow Prep/Camper Package, making its equipment especially interesting for shoppers with bigger hauling or trailering plans. Polished forged aluminum wheels and chrome assist steps give this long-box Sierra a sharp finishing touch. It is a substantial truck with a comfortable, well-equipped cab to match.

Performance and Mechanical

The Duramax and 10-speed automatic are paired with trailering equipment that takes some of the work out of connecting a trailer. The dual-rear-wheel setup and long box are defining parts of this Sierra, whether you are outfitting it for work or bringing along larger loads.
