GMC Sierra data analysis
Max towing capacity: 13,200 lbs
The GMC Sierra tows 13,200 lbs at most (6.2L V8 with Max Trailering Package), on the 2026 model year. That is three-quarter-ton capacity — large travel trailers, car haulers, two-horse trailers with living quarters. The floor is 12,500 lbs — only 5% under the peak. Any version of this vehicle tows within a trailer-load of any other. That is rank 5 of 51 tow-rated vehicles here — top quartile. The cohort median is 5,600 lbs, so this vehicle sits 7,600 lbs above the middle of the field. Next rung up is the Chevrolet Silverado at 13,300 lbs, 100 lbs clear of this one. Immediately behind: the Ram 1500 at 12,750 lbs. Hitch requirement at full weight: Class V weight-distributing.
What it tows loaded
Plan around 10,550 lbs, not 13,200. The rating assumes one driver and nothing else — no passengers, no cargo, no roof rack, no aftermarket bumper. Tongue weight on a 10,550 lb trailer is 1,320–1,980 lbs, and that lands on payload, not on the tow rating. Payload is not published for every configuration in this record. The yellow door-jamb sticker on the specific vehicle is the governing number. Trailers over 3,000 lbs need their own brakes in most states, and this vehicle is rated well past that, so budget for a brake controller. Anything this pulls needs trailer brakes and a weight-distributing hitch. The tow rating is not the hard part; stopping is. Ratings are manufacturer figures, measured to SAE J2807 where the maker applies it. Check the door-jamb label for the exact VIN before hitching up.
Which configuration hits the number
12 rated configurations across 12 model years (2015–2026). A bolt-on hitch does not raise capacity. The rating is built on cooling, axle ratio, brakes and frame reinforcement fitted at the factory. Sources for these 12 rows: manufacturer filings, covering 12 model years.
How GMC Sierra maximum towing capacity varies
Across 12 configurations recorded for the 2015 through 2026 GMC Sierra, maximum towing capacity runs from 12,500 lbs to 13,200 lbs. The strongest figure belongs to the 2019 GMC Sierra (6.2L V8 with Max Trailering Package) at 13,200 lbs, and the weakest to the 2018 car (6.2L V8 with Max Trailering Package) at 12,500 lbs — a spread of 6%. The narrow spread means any year of the GMC Sierra in this table behaves much like the others, so you can shop on price, condition and mileage rather than chasing a particular model year.
What changed for 2026
Average maximum towing capacity for the 2026 GMC Sierra is 13,200 lbs, against 13,200 lbs for the 2025 car — it held flat. A carry-over year like this usually means no powertrain or structural change, so an older example is the cheaper way into the same specification.
Configurations behind these GMC Sierra numbers
The 2015 through 2026 GMC Sierra entries here span 12 model years of published measurements for this figure. 2026 is the busiest model year in the record with 1 separate measured configuration, which is why a single quoted maximum towing capacity figure for that year is rarely the one that matches the car in front of you. Match the row to the exact drivetrain, body style and engine on the window sticker or VIN before relying on the number, and use the comparison links below to see how those same configurations line up against rival models.
Official Factory Specs vs. AutoSpecData Expert Benchmarks
Factory ratings are measured cold, flat, and empty. These are the numbers we would actually hook a trailer to.
| Measurement | Official factory spec | AutoSpecData expert benchmark | Shop note |
|---|---|---|---|
| Max trailer weight | 13,200 lbs | 10,550 lbs | 80% safety margin. Flat highway, properly equipped, brakes on the trailer. |
| Sustained grade / heat | 13,200 lbs | 9,250 lbs | 70% margin for mountain passes, summer heat, and altitude. |
| Tongue weight at safe limit | — | ~1,250 lbs | 12% of the loaded trailer. Too light and it sways at 65 mph. |
The GMC Sierra benchmark applies our 80% Towing Safety Margin (80% everyday / 70% grades) to the manufacturer's rating. It is a working recommendation, not a factory figure — the door placard and hitch label still win.
