2008 GMC Sierra 1500 towing capacity
The 2008 GMC Sierra 1500 is published in 80 configurations, with tow ratings ranging from 4,300 to 10,500 lb depending on cab, bed, drivetrain, and hitch class. The peak figure (10,500 lb) sits in half-ton plus / heavy-duty truck territory.
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
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 2007
The 2007 GMC Sierra 1500 carried a maximum tow rating of 10,500 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.
