2025 GMC Sierra 2500 AT4X AEV: Factory-Built Off-Road Capability, Now in Right-Hand Drive
The GMC Sierra 2500 AT4X AEV is the ¾-ton truck built for serious work and serious terrain—engineered by GMC and American Expedition Vehicles (AEV) as an integrated system. Autogroup International converts it to mirror-image right-hand drive with ADR compliance and supports Australian owners with a 5-year, unlimited-kilometre warranty.
What AT4X brings
A heavy-duty off-road suspension tune, robust underbody protection and the electronics to place a big truck accurately on poor surfaces—without sacrificing long-haul comfort.
What AEV adds (and why it matters)
- Stamped-steel bumpers with integrated recovery points, serious skid plates and beadlock-capable wheels paired with the right tyres. It’s a factory-validated package where geometry, protection and calibration are designed to work together.
- Powertrains & use-cases Choose high-torque diesel or big-capacity petrol (availability varies by build). The brief is the same: tow the heavy loads, carry the heavy loads, and maintain confidence when the road ends—without rebuilding the truck from scratch.
Why factory-developed beats aftermarket
- Integration: Cameras, ADAS and electronics remain harmonious.
- Durability: Off-road geometry and protection are tested as a system.
- Compliance: ADR alignment baked in with our RHD conversion.
- Warranty: Clear support pathways—no finger-pointing between parts.
