2018 GMC Sierra 1500 Crew CAB towing capacity
The 2018 GMC Sierra 1500 Crew CAB is published in 8 configurations, with tow ratings ranging from 6,300 to 11,700 lb depending on cab, bed, drivetrain, and hitch class. The peak figure (11,700 lb) sits in half-ton plus / heavy-duty truck territory.
The table below lists every trim of the 2018 GMC Sierra 1500 Crew CAB 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.
