The table below lists every trim of the 1999 Infiniti QX4 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.

Per-trim breakdown

No per-trim spec breakdown is available for this model year — the headline tow rating shown above is the only figure on file. The model's year-by-year history page may have richer data: Infiniti QX4.

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 Infiniti QX4 carried a maximum tow rating of 5,000 lb. The 1999 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 1998 Infiniti QX4 page for the full per-trim breakdown of the prior year.
