ENGINEERED TO DOMINATE

The 2022 Sierra Heavy Duty pickup truck offers up to 16,329 KG (36,000 LB.)^† of available max. towing. It’s built strong so you can tow strong. Its large drive shaft and rear axle will give you durability and strength. And its brakes and steering offer excellent control.

ADVANCED ENGINES & TRANSMISSIONS

The 2022 Sierra Heavy Duty truck features advanced engines and transmissions that power a confident driving and trailering experience:

6.6L V8 Gas Engine
Available 6.6L Duramax^® Turbo-Diesel V8 Engine with Allison^®† 10-Speed Automatic Transmission

AT4 & DENALI’S HEAVY DUTY CAPABILITY

RESPONSIVE SUSPENSIONS

AT4 & Denali’s independent front suspensions provide excellent wheel alignment, ride comfort and turnability
Live-axle suspension includes two-stage, semielliptic multileaf rear springs to balance payload management and ride quality

OPTIMAL ENGINE PERFORMANCE

To help maintain optimal operating temperatures of the available 6.6L Duramax^® Turbo Diesel V8 engine, a massive 28" variable-speed cooling fan is used. Dense, cool air from the Dual Path Air Induction System is drawn through both the hood scoop and the large grille to maximize horsepower and help optimize trailering performance. The factory-installed Diesel After-Run feature is designed to help cool down the engine following heavy usage.
