The 2025 GMC Sierra HD offers seven distinct trims to match your needs. The Pro is your no-frills workhorse with the standard gas engine. The SLE adds modern tech like a 13.4-inch touchscreen and Google-enabled infotainment. The SLT brings leather seats and luxury accents. The AT4 and AT4X deliver off-road prowess with suspension lifts and rugged features. At the top, Denali offers premium leather and refinement, while Denali Ultimate-standard with the Duramax diesel-combines luxury with maximum capability, including massaging seats and a head-up display.
