The towing capacity in the 2011 GMC Sierra 1500 ranges from 4,400 – 10,700 lbs. This is dependent on the cab size, bed size, drive, package, and most importantly engine.
The highest towing capacity in the 2011 GMC Sierra 1500 of 10,700 lbs is achieved with the 6.2L V8 Engine Extended Cab Standard Bed with Max Trailering Package.
You should always use your own data to determine your towing capacity by calculating towing capacity on your own by using the weight capacities listed in your truck door.
Information in this guide was taken from the 2011 GMC Sierra 1500 Owner’s Manual, the 2011 GMC Sierra 1500 Trailering Guide, 2011 GMC Sierra Denali Owner’s Manual, and the 2011 GMC Sierra 1500 e-brochure.
Though I tried to make this information as accurate as possible, you should always check your manual or contact your local dealer to determine the appropriate towing capacity of your vehicle and necessary equipment.

There are 5 available engines in the GMC Sierra 1500. Not every trim is available with each engine, but there are definitely a lot of choices.

We will walk you through the specs of each to help you decide what engine you want, or identify what engine you have if you already have your truck.

- Trailering Hitch Platform
- 7-wire harness
- 7-way sealed connector
- Automatic Locking Rear Differential
- External Transmission Oil Cooler
This package has no influence on the max towing capacity, but it makes the GMC Sierra capable of towing because it provides the necessary equipment.

- Heavy Duty Automatic Locking Rear Differential

Max Towing Capacity by Engine
To determine the towing capacity of your vehicle, you need to know the:
- engine type
- bed size
- cab size
- drivetrain
- axle ratio
If you know all of these items, then move on to the next section by engine to determine your towing capacity.
If not:
- Start with the VIN decoder from Autozone to determine the engine in the vehicle
- measure the bed size with a tape measure to determine whether you have a 5 ft 9.9 in, 6 ft 7 in, or 8 ft bed
- The cab size should be evident by whether or not the back doors are full-sized
- Drivetrain should be determined with the VIN as well
- The axle ratio will likely be listed on the side of the driver’s door on the certification sticker
You can find the GVWR and usually the axle ratio on the Safety Compliance Certification Label on the inside of the driver’s side door.

GMC recommends that the hitch weight for conventional towing should be 10%-15% of the loaded trailer weight. More so, the fifth-wheel or gooseneck tongue weight should be 15% – 25% of the total loaded trailer weight.
The maximum tongue weight for a conventional weight-distributing hitch is 1,100 lbs.
A loaded trailer exceeding 2,000 lbs must be equipped with its own brake system, with brakes working on all axles.
You must make sure you have the appropriate hitch receiver to accommodate the towing capacity you are targeting.
