The 2025 GMC Sierra HD comes in seven distinct trim levels, each tailored to different priorities:

**Pro** - the capable baseline focused on work-ready performance
**SLE** - adds modern comfort, touchscreen, and trailering tech
**SLT** - brings leather seats and upscale interior refinements
**AT4** - adds factory lift, all-terrain tires, and 4WD for off-road adventure
**AT4X** - extreme off-road performance with locking differentials and 35-inch tires
**Denali** - luxury touches including heated/ventilated seats and premium materials
**Denali Ultimate** - the pinnacle with Duramax diesel standard, massaging seats, and suede leather

Each trim features GMC's 13.4-inch tablet touchscreen and 12.3-inch digital display (where available). Browse current inventory or call (715) 833-0444 to discuss which trim fits your needs best.
