The 2025 GMC Sierra HD offers seven trim levels to match your priorities. **Pro** is the no-frills workhorse baseline with the standard gas engine and tough, functional design. **SLE** adds creature comforts like the 13.4-inch tablet-style touchscreen, Google-enabled infotainment, and enhanced trailering tech. **SLT** brings upscale touches-leather seats, automatic climate control, and refined styling. **AT4** targets off-road adventurers with a factory lift, Rancho shocks, all-terrain tires, and 4WD. **AT4X** (with optional AEV Edition) pushes extreme off-road capability with locking differentials and 35-inch terrain tires. **Denali** and **Denali Ultimate** deliver luxury refinement with genuine leather, premium tech, and heated/ventilated seats.
