6 Tough Highlights of the 2025 GMC Sierra HD

1. 6.6L Engine Options

A 6.6L V8 gas engine comes standard on the GMC Sierra 2500 and 3500 HD, offering an incredible 401 horsepower at 5200 rpm and 464 lb-ft of torque at 4000 rpm. To get the most power out of your GMC Sierra HD, you can choose the available 6.6L Duramax turbo-diesel engine, which yields 470 horsepower at 2800 rpm and 975 lb-ft of torque at 1600 rpm. This engine provides a maximum towing capacity of 21,870 pounds on the 2500 and 36,000 pounds on the 3500.

2. Allison 10-Speed Automatic Transmission

Every GMC Sierra HD pickup comes with an electronically controlled Allison 10-speed automatic transmission with overdrive for the smoothest performance you can imagine. The Allison transmission provides better control and improved cooling when towing and hauling heavy loads, thanks to its tow/haul mode.

3. Trailering Package

The GMC Sierra HD is a popular choice for drivers who have frequent towing projects because it comes with a complete trailering package. The GMC trailering package includes the following features to enhance all of your trailering jobs:

  • Trailer hitch
  • Trailering hitch platform
  • 2.5-inch receiver hitch
  • 4-pin and 7-pin connectors
  • 7-wire electrical harness
  • 7-pin sealed connector

The GMC trailering package also comes with Hitch Guidance, a digital towing feature that lets you view your trailer and hitch on an in-cabin display. When attaching the trailer to the hitch, you can see a visual guideline on your display screen that allows you to attach the two with perfect precision.

4. GMC Sierra HD Pro Safety

GMC Sierra HD pickups come with an exclusive safety package that goes above and beyond to protect you from common causes of accidents. The Sierra HD Pro Safety package uses assistive functions like automatic emergency braking, front pedestrian braking, and forward collision alert to prevent collisions. The GMC Sierra HD Pro Safety package also includes Buckle to Drive, lane departure warning, and IntelliBeam automatic high beams.

5. Available GMC MultiPro Tailgate

The available GMC MultiPro tailgate elevates your hauling experience in the new Sierra HD by offering six possible configurations to accommodate different types of cargo. You can fold the top portion outward to create a set of steps or fold this portion down when the tailgate is closed to haul long items like pieces of wood. The MultiPro tailgate also has a power lock and release function.

Meet the 2025 GMC Sierra HD: Built for Big Jobs

Capable Standard Powertrain

Pop open the base GMC Sierra HD’s hood, and you will find a 6.6L gas V8 that pumps out 401 horsepower and 464 lb-ft of torque. It pairs with the iconic 10-speed Allison automatic transmission, which makes handling heavy loads effortless with smooth gear changes, a special Tow/Haul mode with reduced shift cycling, and Auto Grade Braking. A work-ready RWD system is standard, but drivers who frequently operate in less-than-ideal conditions can opt for the available traction-rich 4WD configuration.

Beefy Diesel V8 Option

Drivers seeking optimum heavy-duty performance should opt for the available 6.6L Duramax Turbo-Diesel V8. This immensely capable machine kicks out 470 horsepower and 975 lb-ft of torque, and, just like the gas V8, it is linked to a 10-speed Allison automatic transmission. When equipped with the diesel V8, the Sierra 2500 HD supports a towing capacity of 21,870 lbs, and the Sierra 3500 HD supports a mind-boggling 36,000 lbs.

Advanced Trailering Technology

The GMC Sierra HD features a sophisticated suite of trailering technologies that gets you through a workday comfortably. For instance, available adaptive cruise control factors in the hitched trailer’s drag coefficient when determining throttle and braking distance, and available trailer side blind zone alert notifies drivers when a vehicle approaches either side of the trailer. An in-vehicle trailering app (standard on all models above the SLE trim level) provides pre-departure checklists, trailer mileage readouts, and tow/haul reminders.

The pickup truck also features several standard and available cameras that help drivers monitor their surroundings. The rearview camera comes with an integrated hitch guidance system that helps you line up the pickup truck’s hitch to the trailer. Additionally, an available camera system with up to 14 views streams footage of the truck bed, trailer, and traffic on the infotainment screen.

Excellent Build Quality

Both the GMC Sierra 2500 HD and 3500 HD are built to endure the extreme stress of heavy-duty work. The pickup truck features a fully boxed frame, which is made of high-strength steel, and a hydroformed front section, which provides a better strength-to-weight ratio than traditional stamped steel structures. Additionally, the pickup truck’s bed is made from roll-formed high-strength steel, allowing you to haul heavy payloads for years to come.

The GMC Sierra HD packs the muscle and technology to turn your workday into a breeze. Talk to our finance team to get pre-approved for an auto loan and make this heavy-duty pickup truck yours today at Dorsey-Jones GMC in El Reno, OK.

The base configuration of the GMC Yukon XL accommodates eight in three spacious rows, featuring bucket seats in the first row and power-release bench seats in the second and third rows.

There are 44.5 inches of legroom and 42.3 inches of headroom in the front row, so tall drivers don’t need to worry about feeling cramped.

Large Cargo Area to Haul Plenty of Luggage

Behind the rearmost seats, you will find a massive cargo area that fits 41.5 cubic feet of luggage. A standard AutoSense power liftgate makes loading and unloading easier, and a collapsible cargo area organizer helps you securely store smaller items. Folding the third and second-row seats expands the cargo volume to a whopping 144.5 cubic feet, preparing the SUV to haul home improvement supplies, camping gear, or even a large mountain bike.

Comfort and Convenience for All Occupants

Long-range comfort comes standard in the GMC Yukon XL. At entry level, the SUV offers perforated leather seats with 8-way power adjustment, heating, and ventilation for the front row and heating for the second row. Standard in-cabin amenities include tri-zone automatic climate control, wireless phone charging, USB charging ports, and a Bose CenterPoint Surround 10-speaker audio system.

The G<C Yukon XL makes a great impression wherever it shows up. The behemoth SUV features a muscular build with sharp body contours and a high ground clearance. A massive black grille with horizontal slats, vertical LED headlamps with animated lighting, and a stylish hood with chiseled lines give the vehicle’s front fascia a confident, squared-off look. By default, the SUV rides on 20-inch Carbon Flash Metallic wheels, but drivers can choose from a range of alternatives, including several 24-inch options.

7 Signs It's Time for a New GMC Engine Air Filter

As you drive, your car’s engine needs a steady supply of fresh oxygen, which is drawn into the system and mixed with fuel inside the combustion chambers. At the same time, it’s important that dust and dirt are kept out by the air filter. If this filter clogs up and restricts the airflow, your engine will start to malfunction. As soon as you first notice signs of a worn-out filter, head to your local GMC dealership for a new one.

7 Signs It’s Time for a New GMC Engine Air Filter

Misfiring Spark Plugs

When less air is allowed to enter the engine by a clogged filter, the precise fuel-air balance is thrown off. This leads to excess fuel inside the cylinders, which will eventually foul the spark plugs, preventing them from firing properly. As your engine misfires, you’ll feel it shudder and hear it sputter and cough alarmingly.
