Exterior Design & Features

Heavy Duty Equipment

The 2022 versions of the GMC 2500HD and 3500HD are equipped with everything they need to live up to its heavy duty designation. Some of the features included to help 2022 GMC Sierra Heavy Duty truck owners to get the most out of their purchase will include:

  • Advanced Lighting: GMC designers have employed LED technology to the trucks’ headlights, taillights and daytime running lights across several trim grades. Additionally, a few trims also use LED foglights and offer LED lights in the cargo bed.
  • Specialized Air Induction: Customers choosing the available turbocharged diesel engine platform will see a different hood style. The Dual Path Air Induction System helps the engine collect cool, dense air that will help boost performance while towing.
  • Bed Step Assist: A side-mounted step is standard equipment on all 2022 Sierra Heavy Duty trucks that will help people access items in the cargo bed.
  • Trailering Mirrors: Towing several tonnes requires a lot of support. Specialized trailering mirrors are standard equipment to make sure the driver can always keep a close eye on what they’re pulling.

Performance & Capability

Heavy-Duty Powertrain Options

The heavy-duty designation applied to the 2022 version of the GMC Sierra 2500 and 3500 is all about power, comfort and capability. GMC takes its work very seriously and that is quite clearly reflected in two heavy-duty powertrain options that are available with the trucks. A naturally aspirated 6.6-litre V-8 engine is standard and a turbocharged 6.6-litre Duramax diesel engine is available on several trims. Both engines are mated to a 10-speed automatic Allison transmission.

Functional Capability

Having a powerful engine is important to delivering functional heavy-duty capability, but it’s not everything. GMC HD trucks also feature the kind of supporting equipment to provide a comprehensive package.

  • The AT4 and Denali models employ independent front suspension for enhanced wheel alignment, ride comfort in most conditions and enhanced maneuverability.
  • Sierra HD models with live-axel suspension include two-stage, semielliptic multi-leaf rear springs for better payload balance management and a higher quality ride.
  • The Duramax® Turbo Diesel engine also uses a large cooling fan to support heavy-hauling needs.

Stopping Power

The ability to pull the heaviest loads is great. But, if the truck and what it’s pulling can’t safely come to a stop, nothing else much matters. GMC engineers have equipped its heavy-duty platforms with a wide range of standard and available equipment to safely control a truck and trailer unit that is pushing the envelope of its capabilities. The Sierra HD models can feature:

  • Auto Electric Parking Brake Assist
  • Park Grade Hold Assist
  • Digital Variable Steering Assist
  • 2-Speed Autotrac Transfer Case (available)
  • Traction Select System (with Tow/Haul and Off-Road Mode) (available)
