2008 GMC Sierra 1500 Towing Capacity & Tow Rating

The table below lists every trim of the 2008 GMC Sierra 1500 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

Tow ratings at this level are normally achievable with a conventional Class II or Class III receiver hitch. Always verify your vehicle has the manufacturer's tow package installed if you intend to tow at the upper end of the rating, and inspect the door-jamb sticker for the actual maximum permitted on your specific configuration.

How this year compares to 2007

The 2007 GMC Sierra 1500 carried a maximum tow rating of 8,600 lb. The 2008 model carries the same headline figure — manufacturers usually leave the rating alone year-over-year unless there's a powertrain or hitch change. See the 2007 GMC Sierra 1500 page for the full per-trim breakdown of the prior year.
