4WD Crew Cab Standard Box AT4
Description
Take on work and adventure with confidence in this 2024 GMC Sierra 2500HD AT4 4WD Crew Cab 159" — a heavy-duty truck built for capability, comfort, and off-road attitude.
Designed with bold AT4 styling and serious 4WD performance, this Sierra is ready for demanding jobs and weekend escapes alike. Equipped with the Gooseneck/5th Wheel Package, stamped bed holes with caps, and a factory 7-pin trailer harness, it’s set up to tow with ease. The durable spray-on bedliner helps protect your investment, while the integrated trailer brake controller gives you added control and confidence when hauling heavier loads.
Inside, you’ll find a refined and tech-forward cabin built for modern driving.

The 13.4" infotainment display ensures everything you need is clearly visible and easy to access on the go.
Comfort is just as important as capability, and this AT4 delivers with heated driver and front outboard passenger seating — perfect for those colder Canadian mornings. The spacious Crew Cab configuration provides generous room for passengers, making this truck just as practical for family life as it is for job sites.
