2018 GMC Sierra 3500hd towing capacity
The 2018 GMC Sierra 3500hd is published in 44 configurations, with tow ratings ranging from 13,000 to 14,500 lb depending on cab, bed, drivetrain, and hitch class. The peak figure (14,500 lb) sits in half-ton plus / heavy-duty truck territory.
The table below lists every trim of the 2018 GMC Sierra 3500hd 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
Ratings in this range are typically achievable with a weight-distributing hitch and the appropriate tow package. The conventional bumper-pull rating without weight distribution will be lower than the headline figure shown here — usually 5,000 to 8,000 lb. Confirm the hitch class on your vehicle's door-jamb sticker before towing at the upper end.
How this year compares to 2017
The 2017 GMC Sierra 3500hd carried a maximum tow rating of 15,000 lb. The 2018 model is rated 500 lb lower — sometimes a real spec change, sometimes a re-test under a stricter standard like SAE J2807. See the 2017 GMC Sierra 3500hd page for the full per-trim breakdown of the prior year.
