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

GMC is a truck brand. The founders, Max and Morris Grabowsky, created GMC 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. For 2024, the Sierra Heavy Duty features enhanced trailering technology. 

An Updated Turbocharger

With a new turbocharger and a 10-speed Allison transmission, the venerable 6.6-liter Duramax turbo-diesel V8 in the Sierra HD Duramax 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% of low-end torque. 

A Smarter Transmission

The 10-speed Allison transmission also replaces the outgoing 6-speed automatic in the 6.6-liter gasoline engine and 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, which gives drivers more confidence when merging onto the highway or even just driving around town. 

A Jump On The Competition

That’s not all the good news that gives the 2024 Sierra HD a jump on 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 significant 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

All of these improvements add up to give the 2024 GMC Sierra 2500 HD Crew Cab a best-in-class max towing performance of 22,070 lbs, and 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

Any buyer who is looking to tow recreationally or professionally knows that 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.
