2023 GMC Sierra 3500 Towing Capacity, Diesel Engine

The 2023 GMC Sierra 3500 is the largest truck in the lineup and delivers the best towing capacity. So, if you need to haul more than 30k pounds, this is the right vehicle to do it. Well, before it is capable of doing it, you must upgrade the drivetrain. That is why a diesel engine is way more popular in the HD segment. While other vehicles are dropping oil burners and testing clean electric powerplants, the Sierra 3500 and other Series 3 trucks will continue to use diesel power.

The pickup is a mechanical twin of the Chevy Silverado 3500. Anyway, the 2023 GMC Sierra 3500 has more premium options, so we consider it as the upscale model. But, it is not a luxury truck. It can be if you pick the Denali package. Still, more buyers will spend the same amount of money to take the off-road AT4 version. The upcoming Sierra 3500 will adopt the new AT4x bundle, like other GMC vehicles.

Specs and Towing Capacity

As said, the 2023 GMC Sierra 3500 is the best hauler in the family, and one of the best trucks for towing in the market. A 6.6-liter Duramax V8 turbodiesel is the first requirement if you want to maximize the potential of the pickup. The Allison transmission is sending power to rear wheels, or all four corners, at the buyer’s choice. A dual-rear-wheel configuration is the next step in the build which will make 2023 Sierra 3500 tow 35,500 pounds.

A petrol engine is a good alternative, if you don’t need so much of a hauling potential. A 6.6-liter gas mill can still make the truck tow 24,000 pounds. General Motors engineers recently introduced this mill instead of a 6.0-liter displacement, to compete better with the Ford Super Duty lineup, which now features a 7.3-l V8. Instead of the Allison 10-speed gearbox, the petrol engine is paired with a 6-pace transmission. This choice will save you about $10,000.
