The table below lists every trim of the 2000 GMC Sierra 3500 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 1999

The 1999 GMC Sierra 3500 carried a maximum tow rating of 9,000 lb. The 2000 model adds 4,800 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 1999 GMC Sierra 3500 page for the full per-trim breakdown of the prior year.
