The 2025 GMC Sierra HD comes in seven distinct trims, each designed to match different work styles and preferences.

Start with **Pro** for straightforward, no-frills capability-ideal if you prioritize durability and performance on job sites. **SLE** adds comfort tech like a 13.4-inch tablet touchscreen and Google integration. **SLT** brings leather seats and refined styling. For off-road adventures, **AT4** features a factory lift, Rancho shocks, and all-terrain tires, while **AT4X** (with optional AEV Edition) offers locking differentials and 35-inch terrain tires for extreme trails.

At the luxury end, **Denali** combines premium leather, heated/ventilated seats, and upscale touches, while **Denali Ultimate**-the top trim-comes standard with the powerful Duramax diesel, massaging seats, and a head-up display.

Each trim pairs with your choice of engine: the standard 6.6L V8 gas or optional Duramax 6.6L Turbo-Diesel. Ready to explore? Call Markquart Motors at (715) 833-0444 or browse our Sierra HD inventory online to find your perfect match.
