To handle the most demanding heavy-duty jobs in Decatur, your local GMC dealership offers the 2025 GMC Sierra HD. This V8-powered workhorse is available in both 2500 HD and 3500 HD variants, featuring a durable build and advanced trailering technology.
Heavy-Duty Towing Capabilities
No matter how grueling the job is, there’s a Sierra HD configuration that makes it look easy. Buyers can choose between the Sierra 2500 HD and 3500 HD as well as two V8 engine options, depending on their towing needs.
Sierra 2500 HD
The Sierra 2500 HD effortlessly handles jobs a light-duty pickup cannot. It is powered by a 6.6L gas V8 that generates 401 hp and 464 lb-ft of torque. Buyers seeking the truck’s maximum towing capacity will need to select the available Duramax 6.6L Turbo-Diesel V8, which has an output of 470 hp and 975 lb-ft of torque. The diesel-powered Sierra 2500 HD tows an impressive 21,870 lbs.
Sierra 3500 HD
For jobs that involve towing commercial machinery, the Sierra 3500 HD is the ideal choice. It offers the same engine options as the Sierra 2500 HD, so you can configure it based on your work needs. Equipping the pickup truck with the Duramax 6.6L Turbo-Diesel V8 enables it to tow a jaw-dropping 36,000 lbs.
Driver-Friendly Allison Transmission
An electronically controlled 10-speed Allison automatic transmission manages both engines’ power delivery. This transmission is widely loved for how it simplifies operation and makes handling heavy loads comfortable. Its functions include a Tow/Haul mode, which reduces shift cycling when activated, and Auto Grade Braking, which reduces reliance on the brake pedal to slow the vehicle on downhill grades.
Excellent Build Quality
Both 2500 HD and 3500 HD variants of the Sierra HD are built to withstand the long-term stress of heavy-duty towing. The pickup truck comes with a fully boxed frame made from high-strength steel. A hydroformed front section significantly improves frontal crash protection compared to traditional stamped steel structures. Additionally, the pickup truck’s bed is constructed using roll-formed steel, enabling it to endure extreme payload weights without deforming.
Advanced Assistance Technology
The Sierra HD is equipped with a suite of advanced trailering technologies that turn even the toughest jobs into a breeze. For instance, it features a ProGrade Trailering System with hitch view, hitch guidance, and an in-vehicle trailering app. Available adaptive cruise control accounts for the additional drag and weight of a hitched trailer, enabling drivers to use the assistance technology while trailering. The Sierra HD also offers an available camera system with up to 14 views.
