The table below lists every trim of the 2024 GMC Sierra 2500 with the engine, drivetrain, axle ratio, horsepower, torque, GVWR, curb weight, and payload that go with that trim's headline tow rating. Manufacturers often publish more than one tow figure per truck — a conventional bumper-hitch rating, a weight-distributing rating, and a gooseneck or fifth-wheel rating — so the highest number here is the maximum across all hitch classes the source carries for the trim.

How to interpret the headline tow figure

Tow figures this high require a gooseneck or fifth-wheel hitch installed in the bed of the truck, and a corresponding trailer setup. Conventional bumper-pull towing on the same vehicle is typically capped well below this number — usually under 15,000 lb. Always check the door-jamb sticker and owner's manual for the maximum permitted on each hitch class before hooking up.

How this year compares to 2023

The 2023 GMC Sierra 2500 carried a maximum tow rating of 18,500 lb. The 2024 model adds 3,550 lb on top of that — usually a sign the manufacturer added a tow package option, refreshed the powertrain, or revised hitch class certification. See the 2023 GMC Sierra 2500 page for the full per-trim breakdown of the prior year.
