The table below lists every trim of the 2004 GMC Sierra 2500 Regular 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.
