The 2025 GMC Sierra HD comes in seven trim levels, each designed for different priorities and lifestyles.

**Work-First Trims:** Pro is the no-frills workhorse baseline, while SLE adds modern comfort and connectivity with a 13.4-inch touchscreen and Google-enabled infotainment.

**Balanced Options:** SLT brings leather seats, automatic climate control, and chrome accents for drivers wanting comfort without sacrificing capability.

**Off-Road Ready:** AT4 includes a factory lift, Rancho shocks, all-terrain tires, and 4WD. AT4X pushes further with Multimatic dampers, locking differentials, and optional AEV rugged enhancements.

**Luxury Tier:** Denali and Denali Ultimate offer genuine leather, heated/ventilated seats, wood accents, and premium tech. Denali Ultimate includes the Duramax Diesel engine standard and 16-way massaging front seats.

Each trim shares the same available engines and core capabilities-the differences are in materials, styling, and convenience features. Visit Markquart Motors in Chippewa Falls to explore which trim fits your needs. Call (715) 833-0444 or browse current inventory online.
