2020 GMC Sierra 3500 towing capacity

The 2020 GMC Sierra 3500 is published in 26 configurations, with tow ratings ranging from 14,500 to 16,300 lb depending on cab, bed, drivetrain, and hitch class. The peak figure (16,300 lb) sits in serious heavy-duty pickup territory.

The table below lists every trim of the 2020 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

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 2019

The 2019 GMC Sierra 3500 carried a maximum tow rating of 13,700 lb. The 2020 model adds 2,600 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 2019 GMC Sierra 3500 page for the full per-trim breakdown of the prior year.
