American Power. Australian Ready.
The 2025 GMC Sierra 1500 redefines what a full-size pickup can be. From the rugged AT4X with its Multimatic DSSV dampers and electronic lockers to the luxurious Denali Ultimate with massaging seats and Super Cruise technology, there’s a Sierra built for your specific needs. With three powerful engine options – including the torquey 3.0L Duramax diesel – and up to 4,128kg towing capacity, this isn’t just another truck. It’s engineered American capability that doesn’t compromise on refinement or technology.
Built for Australia, Backed by Excellence
Every Sierra 1500 arrives in Australia through Autogroup International’s ISO 9001:2015 certified conversion facility, ensuring full ADR compliance without sacrificing the truck’s core DNA. Our professional right-hand drive conversion process maintains factory safety standards while adapting this American icon for Australian roads. From the AT4’s aggressive off-road stance to the Denali’s premium leather appointments, you’re getting authentic GMC engineering with local support and a full factory-backed warranty. This is American truck capability, delivered Australian style.
