2015 GMC Sierra 3500 HD Crew CAB towing capacity
The 2015 GMC Sierra 3500 HD Crew CAB is published in 8 configurations, with tow ratings ranging from 13,000 to 19,600 lb depending on cab, bed, drivetrain, and hitch class. The peak figure (19,600 lb) sits in serious heavy-duty pickup territory.
The table below lists every trim of the 2015 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.

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 2014
The 2014 GMC Sierra 3500 HD Crew CAB carried a maximum tow rating of 18,000 lb. The 2015 model adds 1,600 lb on top of that — usually a sign the manufacturer added a tow package option, refreshed the powertrain, or revised hitch class certification.
