Vehicle Overview
Rugged luxury, ready for any job site.
Meet the 2026 GMC Sierra 2500 HD AT4 in White — the premium 4x4 that blends serious capability with first-class comfort. Built to go off-road or tow with confidence, it comes standard with 4WD, a locking differential, LT275/65R20 tires, 10.1" ground clearance and a full‑size spare. Inside you’ll find leather heated and cooled power seats (with lumbar support), a heated leather steering wheel, power sunroof, navigation and remote start/keyless entry for everyday convenience. Safety and control are rock solid too — ABS, traction and stability control, multiple airbags and vehicle anti‑theft systems are all standard. Backed by a 3/36 basic warranty and a 5/100 powertrain warranty, this Sierra AT4 is ready to work — call or stop by and I’ll get you behind the wheel.
