1999 Hummer H1 towing capacity
The 1999 Hummer H1 is published in 4 configurations with a tow rating of 8,440 lb (full-size truck and SUV territory).
The table below lists every trim of the 1999 Hummer H1 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 1998
The 1998 Hummer H1 carried a maximum tow rating of 8,510 lb. The 1999 model is rated 70 lb lower — sometimes a real spec change, sometimes a re-test under a stricter standard like SAE J2807. See the 1998 Hummer H1 page for the full per-trim breakdown of the prior year.
