When customers stop by Cummins GMC in Weatherford, OK, one of the first things they want to know is simple: How much can the 2025 GMC Sierra 2500 HD actually tow? It's a fair question—especially when you're shopping for a truck that's expected to handle real work, real loads, and real Oklahoma conditions.
The Sierra 2500 HD has built a reputation for strength, and the latest model continues that tradition with even more capability, smarter tech, and the kind of confidence that makes tough jobs feel a whole lot easier.

How Much Can the 2025 GMC Sierra 2500 HD Tow?
The heart of the GMC Sierra 2500 HD towing capacity comes down to two things: engine choice and configuration. GMC gives drivers two strong options—a gas V8 and the legendary Duramax Turbo-Diesel. Both bring serious muscle, but the diesel is where the Sierra really stretches its legs.
With the available 6.6L Duramax, the Sierra 2500 HD can pull some impressive numbers. It's built for long hauls, steep grades, and heavy trailers, and it does it all with a smoothness that surprises a lot of first-time HD truck owners. The diesel's torque comes on early and stays steady, which is exactly what you want when you're towing livestock, equipment, or a large travel trailer.
Payload is just as important, especially for drivers who load up the bed with tools, feed, materials, or gear. The 2026 Sierra 2500 payload capacity gives plenty of room to work with, making the truck just as capable on the jobsite as it is on the highway.
