Yes! The 2025 GMC Sierra HD includes two seriously capable off-road trims:

**AT4 Trim**: Features a factory lift, Rancho shocks, all-terrain tires, skid plates, and a robust 4WD system. It's designed for drivers who tackle trails as often as job sites-perfect for moderate off-road work and construction-zone durability.

**AT4X Trim** (with optional AEV Edition): Takes off-road performance to extremes with Multimatic DSSV dampers, locking differentials, and 35-inch terrain tires. The AEV Edition adds stamped-steel bumpers, protective skid plates, and off-road-specific engineering. Built for serious backcountry enthusiasts.

Both trims maintain the Sierra HD's work-truck toughness while delivering trail-ready performance and resilient interior materials for all-day comfort.
