Buy a 2023 GMC Sierra 2500 in Mountain Home


The Sierra 2500 HD is one of GMC's heavy-duty trucks, suitable for tackling the most challenging jobs from Conway to Branson, MO. It delivers incredible torque and horsepower from its two V8 engine choices, resulting in a remarkable towing and payload capacity. The 2023 model shares most of its features with the outgoing model, except for the new front-row adjustable seat belt guide loops.


The GMC Sierra 2500 HD buyers will choose two engines: a 6.6-liter V8 gasoline engine and a 6.6-liter V8 turbo diesel. The gasoline V8 engine produces 401 horsepower and 464 pound-feet of torque, whereas the 6.6-liter turbodiesel V8 makes 445 horsepower and 910 pound-feet of torque. As expected, the diesel engine has a better towing capacity, rated at 27,500 pounds, against the gasoline engine's 24,000 pounds.

Interior & Design

GMC provides a cozy interior inside the 2023 Sierra 1500 HD to ensure you remain comfortable even when tackling rugged terrains. Interior features in this trim include a heated steering wheel, heated and ventilated leather seats, and dual-zone automatic climate control. Crew cab models have impressive rear legroom to provide enough comfort on long trips across Jonesboro and Harrison. This model also has wireless Apple CarPlay and Android Auto for enhanced connectivity on your family adventures. A powerful Bose audio system with a subwoofer provides you with premium sound wherever you go.

Safety Features

The 2023 GMC Sierra 2500 HD has several driver-assistance features to give you peace of mind as you tackle rough terrains. You will easily keep tabs on your surroundings, thanks to the 15 different camera views that provide added safety even when towing. When the passengers in the rear seat obstruct your rearview, you can switch to a rear camera mirror and get a high-definition view of what's behind your vehicle. When the lane departure warning system notices any drifting, it alerts you and takes corrective action to keep you centered on your lane. All models have front and rear park assists that use sensors to make parking this massive truck easier. In addition, this model has a safety alert seat that vibrates or beeps depending on the direction of the potential danger. The SLE, AT4, and SLT models will have Intellibeam auto high beam headlamps that automatically turn on the vehicle's headlights, depending on your surroundings. Other features include automatic emergency braking, lane change alert, rear cross-traffic alert, and teen driver.
