Which 2026 GMC Sierra 1500 Trims Tow Up to 13,000 lb?

Quebec drivers hitching a travel trailer, boat, or equipment trailer to a 2026 GMC Sierra 1500 face a decision the trim badge alone will not answer. Some work-focused trims out-tow the off-road specialists, and the engine under the hood changes the number as much as the trim itself.

This guide breaks down the tow ratings across the 2026 Sierra 1500 lineup, how the four available powertrains shift that number, and which combination fits the way you actually pull a load.

2026 Sierra 1500 Trim, Powertrain, and Towing at a Glance

Powertrain Choices That Actually Move the Towing Number

The standard 2.7 L TurboMax engine on Pro, SLE, and Elevation makes 310 hp and 430 lb-ft of torque through an 8-speed automatic, rated to tow 9,500 lbs (4,309 kg). That is a strong starting point, and it comes with a 5-year/160,000-km Powertrain Limited Warranty.

Step up to the available 5.3 L EcoTec3 V8 (355 hp, 383 lb-ft, 10-speed automatic) and the Pro, SLE, Elevation, and SLT group can be configured to tow up to 13,200 lbs (5,987 kg), well above the TurboMax figure. That jump matters for anyone pulling a larger travel trailer or a loaded equipment trailer on a regular basis.

The 3.0 L Duramax turbo-diesel inline-six (305 hp, 495 lb-ft) trades peak horsepower for low-end torque and better fuel economy: 10.7 L/100 km city and 9.3 L/100 km highway on AT4, versus 15.9 L/100 km city on the gas-powered Denali. Diesel-equipped trims also carry the extended 5-year/160,000-km powertrain coverage.

The range-topping 6.2 L EcoTec3 V8 (420 hp, 460 lb-ft) is available on SLT, AT4, Denali, and AT4X, and standard on Denali Ultimate, but its fuel economy runs highest in the lineup at 16.0 L/100 km city.

Why the Off-Road Trims Tow Less Than the Work-Focused Ones

AT4 and AT4X both cap out at 9,000 lbs (4,082 kg), even with the 420 hp 6.2 L V8 under the hood. Their two-inch factory lift, off-road suspension tuning, and locking differentials prioritize trail clearance over trailer math: AT4 sits at 11.1 in (282 mm) of ground clearance, AT4X at 11.5 in (292 mm).

Denali lands in between at 9,400 lbs (4,264 kg), pairing the 5.3 L V8 with a comfort-tuned suspension rather than off-road hardware.

Payload tells a different story. Pro’s maximum payload is 2,172 lbs (985 kg), while AT4 reaches 2,372 lbs (1,076 kg) and AT4X climbs to 2,472 lbs (1,121 kg). A buyer choosing between maximum tow rating and maximum payload should not assume one trim wins both.

Trailering Tech: Cameras, Hitch Guidance, and Confidence

AT4 and AT4X come standard with HD Surround Vision, Hitch Guidance, Hitch View, Trailer Side Blind Zone Alert, Rear Cross Traffic Braking, and inside/rear trailer camera input. AT4X adds a standard Bed View Camera; it is available on AT4.

An Auxiliary Trailer Camera is available on both trims for a direct view of what is behind the trailer itself. SLE and Elevation add a standard integrated trailer brake controller, available on Pro, while SLT can be built with the available ProGrade Trailering System and its own trailer brake controller.

Cab Comfort and Bed Practicality for Long Tow Days

Pro, SLE, Elevation, and SLT seat up to six with a front bench seat available, useful for a family towing a camper on weekend trips. AT4, AT4X, Denali, and Denali Ultimate seat five with front bucket seats, trading bench space for a centre console and driver-focused layout.

The Short Bed cargo box measures 69.92 in (1,776 mm) long, 71.4 in (1,814 mm) wide, and 22.42 in (569 mm) tall, for 1,781 L of cargo volume, consistent across Pro, AT4, and AT4X. A 91 L (24 gal) fuel tank across the lineup supports the driving range a long tow day demands.

Matching a Sierra 1500 Trim to Your Towing Habits in Quebec

A family towing a camper or boat trailer a few times a season, without a need for off-road hardware, gets the most tow rating per dollar from Pro, SLE, or Elevation built with the available 5.3 L V8 toward that 13,200 lbs (5,987 kg) ceiling.

Someone hauling heavier loads on a regular basis and wanting lower fuel bills should look at the Duramax diesel on SLE, Elevation, SLT, or Denali, trading a bit of tow ceiling for torque and efficiency.

AT4 and AT4X fit drivers who need genuine off-road capability alongside moderate towing, not the drivers chasing the top number. Denali and Denali Ultimate answer for buyers who want premium cabin materials and features like Super Cruise alongside a Denali-level tow rating.
