The 2026 GMC Sierra 2500 HD Handles Heavy-Duty Towing With Ease
Heavy-duty towing separates the 2026 GMC Sierra 2500 HD from the rest of the truck market, and our team wants you to understand what that looks like in real numbers near Avon. This truck spans work-focused Pro cabins all the way to luxury-leaning Denali Ultimate trims, so your priorities shape which configuration fits best. The sections below cover the engines and towing figures that define this year’s GMC Sierra HD models at Joyce Buick GMC.
Power and Performance
A 6.6-liter gas V8 rated at 401 horsepower and 464 lb-ft of torque serves as the standard engine across the GMC Sierra 2500 HD. If your trailers run heavier, the available 6.6-liter Duramax turbo-diesel V8 raises output to 470 horsepower and 975 lb-ft of torque. Both engines pair with a 10-speed automatic transmission.
Technology Features
Every new GMC model treats cabin technology a little differently, and here it's built around monitoring what's behind you. A 13.4-inch infotainment screen and a 12.3-inch digital Driver Information Center anchor the cabin, so you can monitor trailer stats without cluttering your view. Google built-in and wireless smartphone features keep you connected, while available wireless charging and premium audio make longer hauls feel less like work.
Safety Features
GMC Pro Safety covers the core driver-assistance features on the 2026 GMC Sierra 2500 HD, so Forward Collision Alert and Automatic Emergency Braking can help you react before you would on your own. A Following Distance Indicator helps you keep safe spacing while towing, and available HD Surround Vision plus trailering camera views improve visibility around a hitched load. Available Super Cruise adds hands-free support on compatible roads, easing fatigue on long hauls.
Towing and Cargo
Properly equipped, the GMC Sierra 2500 HD can tow up to 22,390 lbs, with payload reaching up to 4,049 lbs, so you can move heavy loads that would overwhelm a half-ton truck. An available MultiPro Tailgate™, LED cargo-bed lighting, and integrated bed steps make loading in low light more manageable. Each trim level adds a different layer of towing hardware or comfort as you move up the lineup.
