The Sierra Heavy Duty pickup truck will offer greater towing capability than the previous generation, with best-in-class max towing up to 35,500 lbs† (vehicle shown max towing 31,200 lbs). It’s built strong so you can tow strong with a larger drive shaft and rear axle that increases durability and strength. A bigger grille and engine fan improve engine cooling. Improved brakes and steering offer superior control.

Before you buy a vehicle or use it for trailering, carefully review the trailering section of the Owner’s Manual.
