Pull Your World With The New 2024 Sierra Heavy Duty’s Enhanced Trailering

Since being founded by Max and Morris Grabowsky in 1911, GMC has been a truck brand. The company was created to specifically build medium and heavy-duty trucks. In 1923, GMC trucks helped rebuild Kantō, Japan, after a 7.9 magnitude earthquake decimated the entire city, destroying all of their only infrastructure: the railway. The innovation of engineering and building some of the best trucks is what drives GMC. And that innovation continues in the Sierra Heavy Duty Truck. For 2024, the Sierra Heavy Duty gets some significant updates, featuring enhanced trailering technology. 

An Updated Turbocharger

The amazing 6.6-liter Duramax turbo-diesel V8 in the Sierra HD Duramax now comes with engine upgrades and improvements and makes 470 horsepower from just 2,800 rpm and 975 lb-ft of torque from only 1,600 rpm. Thanks to the updated engine performance, drivers now have an extra 25% low-end torque. 

A Smarter Transmission

While the previous Sierra HD gas engines made do with a 6-speed automatic, the 2024 models feature a 10-speed Allison transmission in the 6.6-liter gasoline engine, which helps to increase the overall towing capacity of the gas motor Sierra HD models. Because of the better gearing and transmission, the Sierra HD doesn’t have to hunt for the right gear, and it also gives drivers more confidence when merging onto the highway or even driving around town. 

A Jump On The Competition

There is still more good news that keeps the 2024 GMC Sierra Heavy Duty ahead of the competition. The Duramax alone has been updated to add new cylinder heads with improved cooling jackets, a new engine controller, improvements to the reliability of the cylinder head and glow plugs, and a more efficient turbocharger that features a turbo vane actuator with uprated valve springs. Because of the major upgrades, GMC improved the overall power and torque delivery all through the rev range and at all speeds, as well as better engine braking. 

Total Towing Capacity

With all of these improvements, the 2024 GMC Sierra 2500 HD Crew Cab has a best-in-class max towing performance of 22,070 lbs, 22,430 lbs with a gooseneck/fifth wheel, and a max payload of 4,178 lbs. For buyers that need even more, stepping up to the Sierra 3500 brings the total gooseneck/fifth-wheel trailering capability to 36,000 lbs with a max payload of 7,290 lbs. 

A Worthwhile Investment

Ask truck owners all over the country, and they will tell you that whether you are looking to tow recreationally or professionally, a GMC Sierra Heavy Duty truck is one of the best investments you can make. Thanks to the engineering improvements to the Duramax turbo-diesel motor, there isn’t much that you can’t handle with one of the GMC Heavy Duty pickups.
