2017 GMC Sierra 3500 HD Crew CAB towing capacity

The 2017 GMC Sierra 3500 HD Crew CAB is published in 8 configurations, with tow ratings ranging from 13,000 to 20,000 lb depending on cab, bed, drivetrain, and hitch class. The peak figure (20,000 lb) sits in serious heavy-duty pickup territory.

The table below lists every trim of the 2017 GMC Sierra 3500 HD Crew CAB 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.

Per-trim breakdown

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 2016

The 2016 GMC Sierra 3500 HD Crew CAB carried a maximum tow rating of 19,600 lb. The 2017 model adds 400 lb on top of that — usually a sign the manufacturer added a tow package option, refreshed the powertrain, or revised hitch class certification.
