The 2025 GMC Sierra HD comes in seven distinct trims, each tailored to different work and lifestyle needs. The **Pro** is built for serious workloads with rugged durability and essential tech. The **SLE** adds modern comfort and Google-enabled infotainment for long-haul drives. The **SLT** brings upscale materials and leather appointments. Off-road enthusiasts choose the **AT4** (with factory lift and all-terrain tires) or the extreme **AT4X** (with locking differentials and 35-inch tires). For luxury, the **Denali** offers premium leather and heated/ventilated seats, while the **Denali Ultimate** (with standard Duramax Diesel) represents the pinnacle with 16-way massaging seats and a head-up display.

Each trim is engineered around a standard 6.6L V8 gas engine (401 hp) or optional Duramax Turbo-Diesel (470 hp, 975 lb-ft torque). Visit Markquart Motors in Chippewa Falls to explore these trims in person and find your perfect match. Call **(715) 833-0444** or browse our inventory online.
