2018 GMC Sierra 2500hd towing capacity

The 2018 GMC Sierra 2500hd is published in 30 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 2500hd 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 2500hd carried a maximum tow rating of 14,000 lb. The 2018 model adds 500 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 2017 GMC Sierra 2500hd page for the full per-trim breakdown of the prior year.
