The 2025 GMC Sierra HD is the sixth model year for the latest fourth-generation heavy-duty pickup, once again offering a blend of rugged capability, modern technology, and, in the right configuration, upscale comfort as well. Of course, the heavy-duty Sierra is also quite capable when it comes to hauling stuff from A to B. Now, we’re taking a closer look at the 2025 GMC Sierra HD payload capacities.
As expected, Sierra HD buyers have wide range of payload capacities at their disposal depending on the truck’s configuration, drivetrain, engine, and drive type. The model with the highest payload capacity is the 2025 GMC Sierra 3500 HD Regular Cab Long Bed with dual rear wheels (DRW), rear-wheel drive, and the 6.6L V8 L8T gasoline engine, which can carry up to 7,290 pounds. On the other end of the spectrum, the model with the lowest payload capacity is the 2025 GMC Sierra 2500 HD Crew Cab Standard Bed AT4X AEV Edition with four-wheel drive and the 6.6L V8 L5P turbodiesel Duramax engine, which has a payload capacity of just 2,701 pounds. The lower rating is due to the additional weight of off-road components and luxury features included in this special edition model, in addition to the design of said off-road components.
