2020 GMC Sierra 1500 towing capacity
The 2020 GMC Sierra 1500 is published in 33 configurations, with tow ratings ranging from 6,000 to 9,000 lb depending on cab, bed, drivetrain, and hitch class. The peak figure (9,000 lb) sits in full-size truck and SUV territory.
The table below lists every trim of the 2020 GMC Sierra 1500 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 ratings at this level are normally achievable with a conventional Class II or Class III receiver hitch. Always verify your vehicle has the manufacturer's tow package installed if you intend to tow at the upper end of the rating, and inspect the door-jamb sticker for the actual maximum permitted on your specific configuration.
How this year compares to 2019
The 2019 GMC Sierra 1500 carried a maximum tow rating of 9,000 lb. The 2020 model carries the same headline figure — manufacturers usually leave the rating alone year-over-year unless there's a powertrain or hitch change. See the 2019 GMC Sierra 1500 page for the full per-trim breakdown of the prior year.
