Can I get a dually configuration?
Yes, Dual Rear Wheels are available exclusively on the 3500HD model. This extra set of rear tires provides significantly enhanced stability, preventing your truck from being shoved around by heavy highway crosswinds when hauling a massive horse trailer.
What is the maximum payload capacity?
It can haul up to 7,290 lbs of payload when properly equipped. This exceptional structural strength allows you to load heavy pallets of concrete or roofing shingles directly into the bed without bottoming out the suspension.
What bed lengths are available?
You can choose between a Standard Bed or a Long Bed measuring 98.3 inches. The eight-foot Long Bed allows you to haul full sheets of plywood or drywall flat on the floor with the tailgate safely closed. For a complete look at how these bed lengths pair with different cabin sizes, review our 2026 GMC Sierra HD lineup overview.
Is there a factory gooseneck prep package?
Yes, a Gooseneck and Fifth-Wheel Prep Package is available. It features stamped bed holes and an integrated 7-pin harness, allowing you to quickly hitch up a commercial flatbed without paying for expensive aftermarket drilling.

Can I equip a snow plow?
Yes, an available Snow Plow Prep Package adds a 220-amp alternator and robust underbody skid plates. The upgraded electrical output ensures your plow hydraulics operate smoothly without draining the battery during harsh Indiana winter storms.
Does it include a diesel exhaust brake?
Yes, models equipped with the Duramax diesel feature an integrated exhaust brake. This system utilizes turbocharger back pressure to slow the truck down, preserving your physical brake pads and preventing dangerous overheating on steep highway downgrades.
Does it have a transmission oil cooler?
Yes, a heavy-duty air-to-oil transmission cooler is standard. This cooling hardware aggressively sheds heat from the Allison gearbox, keeping the transmission from slipping or failing when dragging heavy equipment up long, steady inclines.
Are extending trailering mirrors standard?
Yes, power-extending trailering mirrors come standard. These motorized mirrors stretch outward at the push of a button, giving you a clear view past the physical edges of a wide camper when changing lanes on I-69.
Does it feature an engine block heater?
Yes, an engine block heater is available for both powertrains. This device keeps the internal engine fluids warm overnight, ensuring the truck starts up instantly and prevents cold-start wear during freezing Marion winter mornings. If you need a winterization check before the snow hits, contact our Marion heavy-duty truck service team.
How many camera views are offered?
The ProGrade system provides up to 14 camera views when properly equipped. This digital suite includes a specialized Hitch View, which allows you to perfectly align your truck with a trailer tongue alone without needing a spotter standing in the dirt. Explore these cameras directly on the official GMC Sierra 3500HD features page.
From unbeatable commercial payload capability to pro-grade trailering technology, the 2026 GMC Sierra 3500HD is engineered for your toughest jobs. Visit Greg Hubler Buick GMC in Marion to discover our heavy-duty inventory or line up your test drive.
