How Much Can Each 2026 GMC Truck Tow?
GMC's 2026 pickups tow anywhere from 7,700 lbs in a properly equipped Canyon to 36,000 lbs in a Sierra 3500 HD dually with a gooseneck hitch.
2026 GMC Canyon
The GMC Canyon towing capacity tops out at 7,700 lbs in crew cab 2WD and 4WD models with the 2.7L TurboMax engine. That's plenty for a fishing boat, a pair of side-by-sides, or a small camper. Off-road trims trade a little in towing capacity for trail hardware: the AT4X is rated at 6,000 lbs and the AT4X AEV Edition at 5,500 lbs.
2026 GMC Sierra 1500
The GMC Sierra 1500 towing capacity reaches 13,300 lbs with the Duramax 3.0L Turbo-Diesel, the Max Trailering Package, and 20-inch wheels. The 6.2L V8 is close behind at 13,100 lbs, while the 5.3L V8 reaches 11,200 lbs and the 2.7L TurboMax up to 9,400 lbs. For most campers and enclosed trailers, the half-ton Sierra has it covered.
2026 GMC Sierra 2500 HD
The GMC Sierra 2500 HD towing capacity reaches 20,000 lbs with a conventional hitch and the Duramax 6.6L Turbo-Diesel V8 and Max Trailering Package. Switch to a fifth-wheel or gooseneck, and it climbs to 22,390 lbs. The 6.6L gas V8 tows up to 16,000 lbs conventionally, a strong option if you don't need diesel.
2026 GMC Sierra 3500 HD
The GMC Sierra 3500 HD towing capacity leads the lineup at up to 36,000 lbs with a gooseneck hitch or 32,000 lbs with a fifth-wheel on a regular-cab dually with the Duramax and Max Trailering Package. Conventional towing maxes out at 20,000 lbs. It's built for livestock trailers, equipment haulers, and big fifth-wheel campers.
GMC Hummer EV Pickup and Sierra EV
The GMC Hummer EV towing capacity reaches up to 12,100 lbs on a properly equipped Hummer EV Pickup 2X, or 7,500 lbs with the Extreme Off-Road Package.
The Sierra EV tows up to 12,500 lbs in Extended Range form. Both are sold through GMC EV dealers, and towing reduces electric range, so plan charging stops accordingly.
This GMC towing capacity chart puts each truck's top 2026 rating side by side.

Why Do Drivers Love GMC Trucks for Work and Everyday Life?
GMC trucks pair serious capability with the comfort and technology that make them easy to live with all week. The same Sierra that pulls a skid steer on Friday can handle school drop-off and a grocery run on Saturday.
On the work side, the available ProGrade Trailering System includes Hitch View and the In-Vehicle Trailering App, which helps with hookup checklists, trailer maintenance reminders, and trailer tire pressure monitoring. The 10-speed automatic available in Sierra models includes Tow/Haul mode and grade braking for steadier control on long descents. For daily driving, trims like SLT, AT4, and Denali bring upscale interiors, while the MultiPro tailgate, standard on Sierra HD trims above the Pro, makes loading easier. Around Yankton, where winter roads and gravel are part of life, available 4WD adds year-round confidence.
What Affects a GMC Truck's Real-World Towing Capacity?
Cab style, bed length, drivetrain, engine, axle ratio, wheels, and factory packages all change a truck's rating.
The Max Trailering Package for GMC Sierra 1500 models is a big factor. It adds a 9.76-inch rear axle, a 3.42 axle ratio, an enhanced radiator cooling system, revised shock tuning, heavier-duty rear springs, and a 220-amp alternator. Weight counts too: passengers, cargo, and accessories all reduce what's left for the trailer. For an exact figure, look up the GMC towing capacity by VIN. The Northtown Buick GMC team can run your VIN to confirm the factory build, and your owner's manual and door-jamb labels list key weight ratings.
