Performance and Trailering

No matter what you need to haul, the Sierra 3500 HD has you covered. Several options allow you to customize to your needs, like three cab sizes (Crew, Double, and Regular) and two bed lengths (6’9” Standard and 8’ Long). Dual rear wheels are available at certain trim levels, and an upgrade from the standard 6.6L V8 Gas Engine gets you the most power. When you choose the 6.6L Duramax Turbo-Diesel V8 Engine, you get a max payload up to 6,196lbs and max trailering up to 36,000! An automatic rear locking axel is standard, and more trailering packages are available to lend a hand on the road. The GMC Standard Multi-Pro Tailgate and integrated brake controller are standard on most trims and available on others, allowing for the ultimate control when you’re hauling a heavy load.

Interior Features

Inside, the Sierra 3500 HD is filled with standard and available features to make your ride more comfortable, safe, and entertaining. The elevated driver seat gives you a wider view of the road, while the Crew Cab option offers Best-in-Class head and legroom for your passengers. Store extra belongings in the available cargo areas around the interior, or choose the AT4 or Denali for exclusive interior styling and designs. All interiors include a 7 or 8-inch GMC Infotainment System with Bluetooth connectivity with an available wireless charging pad to give you power on the go. More available upgrades like a heated steering wheel and heated/ventilated front seats give a premium feel during every trip.
