Built for the heavy lifting, yet refined enough to make every kilometre feel first class. At Garage Tardif in Amos, this new 2026 GMC Sierra 2500 HD AT4X Crew Cab 4WD is ready for demanding workdays, towing duty and off-road weekends across Abitibi-Témiscamingue. Finished in white and showing only 1 km on the odometer, this truck is poised for its very first real adventure.
Under the hood, the 6.6L gas V8 delivers up to 470 horsepower through a 10-speed automatic transmission and four-wheel drive. It brings the confident muscle needed for hauling equipment, towing with control and travelling through challenging Quebec conditions. Its off-road suspension lift, 35-inch mud-terrain tires, protective skid plates and electronically locking rear differential give this heavy-duty 4x4 truck the hardware to keep moving when the road ends.
