2026 Chevrolet & GMC HD Truck Towing Guide in Stratford, ON

2026 Chevrolet & GMC HD Truck Towing Guide

If you need to pull serious weight, hard specifications carry more weight than anything else. A properly equipped 2026 Chevrolet Silverado HD or GMC Sierra HD tows up to 36,000 pounds when equipped with the available Duramax 6.6L Turbo-Diesel V8, which has 470 horsepower and 975 lb-ft of torque working through a 10-speed automatic transmission. But max towing is only useful if you know which cab, bed, and engine configuration gets you there, because the spread between a gas single-rear-wheel 2500 HD and a diesel dually 3500 HD is enormous.

Continue reading as our experts at Stratford Motor Products break down max towing for both GM HD lineups.

Duramax Diesel vs. 6.6L Gas: Which HD Engine Should You Choose?

This is the question that most HD shoppers wonder about, and the answer comes down to how often you're actually near your limit. The available Duramax 6.6L Turbo-Diesel V8 nearly doubles the gas engine's max towing figure. It delivers more than twice its torque, which translates to easier grade climbing and less strain on long hauls. The standard 6.6L V8 gas engine has a lower up-front cost and still pulls 19,080 pounds, more than enough for most equipment trailers, dump trailers and mid-size travel trailers.

Engine Horsepower Torque Transmission Max Available Towing
Duramax 6.6L Turbo-Diesel V8 470 hp 975 lb-ft 10-speed automatic 16,330 kg (36,000 lb)
6.6L V8 Gas 401 hp 464 lb-ft 10-speed automatic 8,655 kg (19,080 lb)

Whichever engine you land on, both HD lineups offer loads of available trailering technology that make towing more convenient and safer:

  • Up to 14 available camera views from 8 available cameras
  • Transparent Trailer View, which lets you see “through” a compatible trailer, even with a fifth-wheel or gooseneck hitch
  • Hitch View for aligning the truck to the trailer in Reverse
  • Bed View for fifth-wheel and gooseneck hitching
  • In-Vehicle Trailering App with custom trailer profiles and pre-departure checklists
  • Trailer Side Blind Zone Alert, which extends side-mirror alerts to the length of your trailer
  • Available Adaptive Cruise Control that accounts for added drag and longer braking distances while towing
