Towing capacity increases 1,900 pounds on 2WD configurations (max. capacity now 9,300 lbs.) and GMC reduces the price by $1,500, which means the diesel now costs a mere $995 more than the gas-powered 5.3-liter V-8.

Heavy-duty trucks are all about capability, and for 2021, GMC increases the maximum towing capacity of its HD trucks by 500 lbs. For those keeping score, when properly equipped, that means it can handle 36,000 lbs. of trailer.

An available Four Corner Air Ride suspension can raise the vehicle up to two inches to provide extra ground clearance, while Magnetic Ride Control adaptive damping helps to deliver a smooth ride and responsive handling.
