The 2025 GMC Sierra HD comes in seven distinct trims, each tailored to different priorities. **Pro** is the workhorse baseline with essential capability; **SLE** adds modern comfort and Google-enabled tech; **SLT** brings upscale materials and leather; **AT4** focuses on off-road readiness with lift and all-terrain tires; **AT4X** pushes extreme trail performance with locking differentials and 35-inch tires; **Denali** delivers luxury touches like heated/ventilated seats and wood accents; and **Denali Ultimate** is the pinnacle, standard with the Duramax Diesel and massaging seats.

Each trim shares the Sierra HD's tough DNA-401 hp gas V8 standard, available Duramax Diesel, 13.4-inch tablet touchscreen, and the innovative MultiPro tailgate. Visit Markquart Motors in Chippewa Falls to explore all trims in person, or call (715) 833-0444 to discuss which fits your needs.
