Performance 

Heavy gear won’t pose a challenge when you harness the strength of the Sierra 2500HD, which boasts a 22,390-lb. maximum towing capacity¹ and a 4,049-lb. maximum payload limit². The foundation of this model’s exceptional skills is a standard 6.6L V8 gas engine that achieves 401 horsepower and 464 lb.-ft. of torque. If your I-81 commute calls for greater intensity, switch to the available Duramax 6.6L Turbo-Diesel V8 powertrain and up the ante to 470 horsepower and 975 lb.-ft. of torque. An optional 4WD system gives this truck the ability to continue moving forward where others would falter. When you venture off the beaten path, utilize the Sierra 2500HD’s available driver-selectable e-locking rear differential to maintain a sturdy grip on uneven terrain.

Exterior 

As you choose your favorite version of the 2026 GMC Sierra 2500HD, consider the number of passengers and amount of cargo that you’ll need to accommodate. While the 2-door Regular Cab will allow you to maximize cargo space during trips to Soldiers and Sailors Memorial Park, a 4-door option like the Double Cab or Crew Cab can provide more room for guests. After making your selection, decide whether the length of your work equipment will require a 82.20- or 98.27-inch bed. Off-road enthusiasts can take the opportunity to equip the Sierra 2500HD with optional twin-tube Rancho® shocks and skid plates.

Technology 

Boring road trips will be a thing of the past with the Sierra 2500HD’s available 13.4-inch touchscreen at your fingertips, supplying easy access to your favorite media options. Employ the optional Google built-in³ assistant to change tracks and route to your destination while keeping your hands on the wheel. The available 12-speaker Bose®⁴ audio system will use Centerpoint⁵ surround sound technology to deliver each beat of your playlist with booming clarity, making you feel like you’re in the front row at a concert. Instead of worrying about untangling cords, you can effortlessly replenish your device’s battery level by placing it on the optional wireless charging pad⁶.
