This truck works harder than your coffee maker on a Monday morning, and it does it with a lot more horsepower. Introducing the 2026 GMC Sierra 2500HD SLT, finished in Glacier White Tricoat and engineered for drivers who expect serious capability with refined comfort. Under the hood, the Duramax 6.6L V8 Turbodiesel delivers exceptional torque, confident towing performance, and proven durability for demanding jobs or heavy recreational use. The SLT trim provides a premium driving experience with advanced technology, upscale materials, and the kind of quiet strength that makes long drives and tough workdays equally enjoyable. This Sierra also includes the 2-Year/24k Young Auto Group Maintenance Plan, featuring two years of free oil changes, free tire rotations, and free safety inspections. Together, these features make this heavy-duty truck a smart, reliable investment for customers who want capability without compromise.

Built to handle tough workloads with confidence, the Sierra 2500HD offers impressive towing and payload capabilities while maintaining stable, controlled handling. The Glacier White Tricoat exterior adds a clean, professional appearance that stands out on the jobsite and looks just as sharp in the driveway. Inside, the cabin is designed for comfort and convenience, offering modern infotainment, intuitive controls, and plenty of space for passengers and gear.
