The GMC Sierra 1500 has four engines:

• A 2.7-liter TurboMax engine makes 310 horsepower and 430 pound-feet of torque.
• A 5.3-liter V8 engine produces 355 horsepower and 383 pound-feet of torque.
• A 6.2-liter V8 engine delivers 420 horsepower and 460 pound-feet of torque.
• A 3.0-liter Duramax Turbodiesel engine generates 305 horsepower and 495 pound-feet of torque.

A properly equipped GMC Sierra 1500 can tow up to 13,300 pounds. The maximum rating comes from configurations equipped with the 3.0-liter Duramax Turbodiesel engine, a great choice for Kingfisher truck shoppers who tow regularly.

Maximum payload reaches 2,230 pounds on properly equipped GMC Sierra 1500 models. Payload varies considerably across the lineup since the engine, cab, drivetrain, trim equipment, and options change the truck's curb weight. Customers from Enid can check the Tire and Loading Information label on the individual truck for its specific payload figure.

Yes. Four-wheel drive (4WD) is available across much of the GMC Sierra 1500 lineup and comes standard on select trims. It's ideal for Oklahoma buyers who regularly travel on gravel, muddy job sites, ranch roads, or snow-covered pavement.

The GMC Sierra 1500 lineup includes:

• Pro
• SLE
• Elevation
• SLT
• AT4
• AT4X
• Denali
• Denali Ultimate

Regular Cab works well when passenger space takes a back seat to bed capacity. Double Cab adds a second row without requiring the larger Crew Cab body. Crew Cab provides 43.4 inches of rear legroom, making it a practical choice for Oklahoma City shoppers who regularly carry family members, coworkers, or clients.

The GMC Sierra 1500 offers a short, standard, and long bed, depending on the cab configuration. Long beds provide up to 89.1 cubic feet of cargo volume. Twelve standard tie-downs give you multiple points for securing equipment, lumber, furniture, and other cargo.

The GMC Sierra 1500 seats up to six people in configurations equipped with a front bench seat. Models with front bucket seats seat five. Regular Cab versions accommodate up to three people.

The available GMC MultiPro Tailgate has six positions and functions. It can act as a conventional tailgate, provide closer bed access, create a load stop for longer cargo, form a step into the bed, and provide a work surface. You can also integrate an available KICKER audio system into the inner gate.

• The GMC Sierra 1500 AT4 uses a 2-inch suspension lift, Rancho monotube shocks, skid plates, and other equipment intended for unpaved terrain.
• The GMC Sierra 1500 Denali takes a road-oriented luxury direction with premium interior materials, distinctive exterior trim, and available Super Cruise.

Edmond buyers deciding between them should consider where the truck will spend most of its miles.

The GMC Sierra 1500 AT4X goes beyond the AT4's off-road equipment, adding Multimatic DSSV dampers and front- and rear-electronic locking differentials. The AT4 already includes a 2-inch lift and useful trail hardware, making the AT4X the more specialized configuration for tougher off-pavement conditions.

Properly equipped GMC Sierra 1500 models can use the available Super Cruise for hands-free driving on compatible roads, including operation while towing. The system uses cameras, sensors, GPS, and map data to manage steering and speed. Availability depends on trim and equipment, so check the exact truck before assuming Super Cruise is included.

Stillwater shoppers can look at the V8 and Duramax powertrains:

• The 6.2-liter V8 engine delivers the highest output at 420 horsepower.
• The 3.0-liter Duramax Turbodiesel generates the highest torque at 495 pound-feet.

Yes. Selected GMC Sierra 1500 configurations use a 40/20/40 split front bench seat, raising total seating capacity to six. Other trims use front bucket seats and seat five. Check the interior photos and equipment list for each truck inventory since seating layouts vary by trim and configuration.
