Duramax Strength Meets Precision Engineering
The 6.6L V8 gas engine produces 401 horsepower and 464 lb.-ft. of torque, paired with an Allison 10-speed automatic transmission and a 3.73 rear axle ratio for smooth, responsive performance.

Towing Made Effortless

Available Adaptive Cruise Control with Trailering adjusts for extra drag and braking distance, delivering a safer, smoother towing experience every time.
