2004 GMC Sierra 2500 towing capacity
The 2004 GMC Sierra 2500 is published in 11 configurations, with tow ratings ranging from 10,000 to 10,800 lb depending on cab, bed, drivetrain, and hitch class. The peak figure (10,800 lb) sits in half-ton plus / heavy-duty truck territory.
The table below lists every trim of the 2004 GMC Sierra 2500 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 2003
The 2003 GMC Sierra 2500 carried a maximum tow rating of 10,700 lb. The 2004 model adds 100 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 2003 GMC Sierra 2500 page for the full per-trim breakdown of the prior year.
