The 2025 GMC Sierra HD comes in seven distinct trims, each designed for different priorities: Pro for pure worksite durability, SLE for comfort plus capability, SLT for refined style, AT4 for serious off-road adventure, AT4X for extreme terrain, Denali for luxury refinement, and Denali Ultimate for the highest standards of comfort and power combined.

Every trim pairs with either a standard 6.6L V8 gas engine (401 hp, 464 lb-ft torque) or an available Duramax 6.6L Turbo-Diesel V8 (470 hp, 975 lb-ft torque). All feature GMC's 13.4-inch tablet-style touchscreen, digital driver display, and MultiPro tailgate.

Whether you prioritize work capability, off-road performance, or luxury appointments, Markquart Motors in Chippewa Falls has the Sierra HD trim for you. Browse our new inventory online or call (715) 833-0444 to discuss which trim matches your lifestyle.
