For 2020, GM rolled out some important updates for the aging platform to keep up with the competition. They did stick with the same L5P engine with some welcome upgrades to the cooling system to help keep things cool when towing heavy loads. Even though the power output was still 445 horsepower and 910 lb.-ft. Of torque, the towing capabilities increased a staggering 52% to 35,500 lbs. This was made possible due to a huge change in the drivetrain, a 10-speed automatic Allison transmission. This allowed the new trucks to handle these heavy loads with ease by keeping them in the power band at all times.
