Updates to the Sierra HD Truck Lineup

In 2022, the GMC Sierra 1500 light-duty pickup truck received a redesign, and 2023 is the year the heavy-duty (HD) Sierra trucks will receive subtle upgrades throughout the model year. The rolling refreshes will include new front and rear end designs, a modernized interior, and upgraded powertrains. At Gill Buick GMC in Madera, our team is excited to see how the automaker changes the 2023 GMC Sierra HD.

Exceptional Performance Features

The 2023 GMC Sierra 2500 HD and 3500 HD models come in five trims: Pro, SLE, SLT, AT4, and Denali. Both trucks have two powertrain choices. The first is a standard 6.6-liter V8 gasoline-powered engine with 401 horsepower and 464 lb-ft of torque. The second is a powerful 6.6-liter V8 Duramax turbo-diesel engine with 445 horsepower and 910 lb-ft of torque. The gas-powered engine is paired to a six-speed automatic transmission while the diesel has a 10-speed Allison Automatic Transmission.

The 2500 HD with the diesel engine, a crew cab, and four-wheel drive has a maximum towing capacity of 18,500 pounds. The gas-powered engine configured with four-wheel drive and a crew cab can tow 14,500 pounds. The 3500 HD models have significantly higher towing capacities based on various configurations.

The Trailering Package is standard on all trims. It includes a Trailer Hitch, Trailering Hitch Platform, a 2.5-inch receiver hitch with 4-pin and 7-pin connectors, and the 7-wire electrical harness with a 7-pin sealed connector for lights and brakes.
