The 2025 GMC Sierra HD offers two distinct off-road personalities:

**AT4 Trim** - The balanced choice. Features a factory lift, Rancho shocks, all-terrain tires, skid plates, and 4WD. Refined yet rugged materials support both construction sites and backcountry roads. Great for truck drivers who blend serious work with occasional trail adventures.

**AT4X Trim** - The serious enthusiast choice. Steps up with Multimatic DSSV dampers, locking differentials, and 35-inch terrain tires for maximum traction. The optional AEV Edition adds stamped-steel bumpers, additional skid plates, and off-road-specific styling. Built for those who demand extreme performance.

Both deliver the aggressive styling and rock-solid resilience you need. Your use frequency and terrain difficulty will guide the choice. Chat with Markquart Motors at (715) 833-0444 to test drive both and find your perfect fit.
