General Motors will soon launch its completely-overhauled portfolio of full-size SUVs across North America and beyond. That portfolio includes the 2021 Chevrolet Tahoe and Chevrolet Suburban, 2021 GMC Yukon and Yukon XL, plus the 2021 Cadillac Escalade and 2021 Escalade ESV.
GM recently revealed the 2021 Chevrolet Suburban towing capacities, allowing us to compile a detailed account of the standard and maximum ratings for all Suburban powertrain choices, and also to compare them to those of the last-generation model. For those wondering what the difference is between the two, the maximum rating applies when buyers check the Max Trailering Package (RPO code HNT).

The new-generation Chevrolet Suburban is built on the GM T1 platform and is equipped as standard with the L84 5.3L V8 that produces 355 horsepower and 383 pound-feet of torque. The optional L87 6.2L V8 generates 420 horsepower and 460 pound-feet. Also available later in the model year will be the Duramax turbo-diesel LM2 3.0L I6, good for 277 horsepower and 460 pound-feet of torque. All three engines are connected to the GM 10-speed automatic transmission, in either 2WD or 4WD configuration.

Standard 2021 Chevrolet Suburban towing ratings have increased by a significant 1,600 to 1,700 pounds, which means many buyers won’t need to opt for the Max Trailering Package anymore. In all cases with the 5.3L V8, the package only adds 400 pounds of extra trailering capacity.

Overall, the maximum 2021 Chevrolet Suburban towing capacity remains unchanged at 8,300 pounds when compared to the last-generation model. It still trails its cross-town rival, the Ford Expedition, which boasts a maximum trailering rating of 9,300 pounds. It also ranks below the Nissan Armada (8,500 pounds), but above the Toyota Sequoia (7,400 pounds).
We should note that towing capacities for the turbo-diesel 3.0L engine are not yet available. However, we did report on the 2021 Cadillac Escalade’s tow ratings, which include the oil-burning inline-six. Those figures should provide an indication of what to expect from the Suburban diesel’s towing ratings.
2021 Chevrolet Suburban production will begin at the GM Arlington plant in Texas in late June, and the very first units will begin shipping to dealers shortly thereafter. Starting prices will range from $52,995 to $76,595 before options. GM’s full-size SUVs boast slightly higher fuel economy in city driving, but are a tad less efficient on the highway.

Those are poor values for what the vehicle is. Forget about the relevant competition – a FULL size, 8-9 passenger, 4WD SUV with the “Max Trailering” package and a 420 hp / 460 ft lbs engine and a 10 speed automatic should have a more substantial tow rating. Just consider that 7,900# is the same as the model with the small engine and withOUT the Max Trailering package. There should absolutely be a 10k package option.
I was not aware the 2015-2020 model year Suburban’s were available with a 3:23 gear ratio. I thought the non NHT vehicles had a 3:08 gear ratio and the NHT vehicles had the 3:42 gear ratio.
Only the late 6.2/10 speed vehicles had the 3.23. Very few. You are correct re the 3.08/3.42 split, except that Z71’s had 3.42’s, also.
You’re absolutely right. The article has been updated.
Bring back the 3/4 ton suburban so I can buy one
