The table below lists every trim of the 2023 GMC Sierra 3500 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 2022

The 2022 GMC Sierra 3500 carried a maximum tow rating of 21,210 lb. The 2023 model is rated 1,210 lb lower — sometimes a real spec change, sometimes a re-test under a stricter standard like SAE J2807. See the 2022 GMC Sierra 3500 page for the full per-trim breakdown of the prior year.
