The 2025 GMC Sierra HD offers seven distinct trims, each tailored to different needs and lifestyles.

**Work-focused trims** start with the **Pro**-a straightforward workhorse with essential tech and durable materials. The **SLE** adds modern comfort with a 13.4-inch touchscreen and Google-enabled infotainment.

**Refined options** include the **SLT** (leather seats, upscale materials) and **Denali** (genuine leather, wood accents, premium touches).

**Off-road trims** feature the **AT4** with a factory lift, all-terrain tires, and 4WD, plus the extreme **AT4X** with locking differentials and 35-inch terrain tires. The **Denali Ultimate** crowns the lineup with the Duramax diesel standard, massaging seats, and luxury appointments.
