The 2026 GMC Sierra 3500 HD brings serious protection to heavy-duty trucking. This powerful pickup includes dual-stage frontal airbags for both the driver and front passenger. Side-impact airbags mount into the seats to guard against crashes from the side. Head-curtain airbags cover the front and rear seating areas. Winnsboro drivers who haul heavy loads will also like the Passenger Sensing System that adjusts how airbags work based on front seat occupants.
