The 2025 GMC Sierra HD offers seven trim levels, each with its own personality. Pro is the work-focused baseline with essential capability and durability. SLE adds modern comfort like the 13.4-inch touchscreen and Google-enabled tech. SLT steps up with leather seats and refined accents. For off-road adventure, AT4 includes a factory lift and all-terrain tires, while AT4X pushes extreme terrain capability with locking differentials and 35-inch tires. On the luxury side, Denali brings genuine leather and premium touches, and Denali Ultimate is the pinnacle-standard Duramax diesel, massaging seats, suede leather, and a head-up display.
