What is the GMC Sierra's towing capacity?
Knowing the towing capacity set by the manufacturer is critical to both the safety of the passengers on board the truck and to the folks you share the road with. Failure to know and follow the towing capacity maximums can result in severe damage to the GMC Sierra's frame, axels, and tow hitch, as well as potentially resulting in your tow load being detached in the middle of the tow. Too much weight being pulled will also place an undue amount of tension on your Sierra's engine. It can also significantly decrease the lifetime of the engine and the transmission.
The towing capacity ranges by trim levels are:
- Sierra 1500, SLE, Elevation, and SLT crew cabs: 7,400-11,800lbs
- Sierra 1500, SLE, Elevation, and SLT double cabs: 9,000-11,300lbs
- Sierra 1500, SLE, Elevation and SLT regular cabs: 7,600-9,900lbs
- AT-4: 8,800-11,800lbs
- Denali: 8,500-9,500lbs
What is the Sierra's maximum payload?
Knowing the difference between a pickup truck's towing capacity and maximum payload can be a little confusing, but it's important to know the difference before you attach a trailer to your GMC Sierra's hitch or start piling cargo into the bed. While the towing capacity refers to how much trailered weight your GMC Sierra can pull behind it, the payload capacity refers to how much weight you can safely place inside the truck itself. This includes not only the bed of the truck, but it combines the weight of who or what is inside the cab as well. Like towing capacity, the payload capacity for the GMC Sierra will vary greatly by the trim level selected, as well as the bed size, cab style, 4x2 or 4x4 styles, and type of engine. The range of payload maximum by trim level is as follows:
- Sierra 1500, SLE, Elevation, and SLT crew cabs: 1,520-2,140lbs
- Sierra 1500, SLE, Elevation, and SLT double cabs: 1,750-2,170lbs
- Sieraa 1500, SLE, Elevation, and SLT regular cabs: 2,020-2,250lbs
- AT-4: 1,540-2,120lbs
- Denali: 1,550-2,040
Ignoring the maximum payload of your GMC Sierra can result in great damage to your pickup truck. Too much weight on board can severely damage your Sierra's frame, axels, and tires. Being overloaded can also put a great deal of strain on your truck's engine and transmission. Should you purchase a GMC Sierra, please consult the owner's manual for the exact manufacturer's recommendations for payload maximums and other safety precautions.
