Maximum Capability. Uncompromised Stability.
When serious towing and hauling are non-negotiable, the 2026 Sierra 3500 HD DRW delivers. Purpose-built with dual rear wheels, it offers two powerhouse engine options: a 6.6-litre Duramax turbo-diesel V8 producing 470 horsepower and 975 lb-ft (1,322 Nm) of torque for maximum pulling strength, or a 6.6-litre petrol V8 generating 401 horsepower and 464 lb-ft (629 Nm) of torque for dependable versatility. Both are paired with a smooth 10-speed automatic transmission. With gooseneck and fifth-wheel towing capability, plus advanced trailer technologies like transparent trailer mode and up to 14 available camera views, the Sierra 3500 HD DRW inspires confidence on every haul. And with Denali and Denali Ultimate trims, capability is matched by premium comfort and refinement. The 2026 Sierra 3500 HD DRW isn’t just GMC’s most capable heavy-duty pickup — it’s Australia’s ultimate towing solution.

Experience The GMC Sierra 3500 HD DRW
PRO
Hardworking pickup designed for maximum utility, offering straightforward strength and capability for tough jobs. Standard power comes from a 6.6L V8 gas engine, with the option to upgrade to the 6.6L Duramax Turbo-Diesel V8 for even greater towing and hauling performance. The dual-rear-wheel configuration delivers outstanding stability and load-carrying confidence, making the Sierra 3500 HD Pro the ideal workhorse for heavy trailers, equipment, and demanding worksites.
SLE
Practical and versatile, the Sierra 3500 HD SLE DRW adds extra comfort and technology while keeping the focus on capability. Powered by a standard 6.6L V8 gas engine or available Duramax turbo-diesel, it’s built to manage serious towing and hauling. Dual rear wheels enhance stability under load, making the SLE an excellent choice for both professional use and everyday dependability.
SLT
Blending capability with refinement, the Sierra 3500 HD SLT DRW delivers premium features without sacrificing toughness. With leather-appointed seating, advanced infotainment, and the choice between a 6.6L V8 gas or Duramax turbo-diesel V8, it’s equipped for both long hauls and long days. The DRW setup provides superior confidence when towing heavy equipment or livestock across Australia’s demanding terrain.
AT4
Purpose-built for rugged work and play, the Sierra 3500 HD AT4 DRW combines off-road capability with heavy-duty performance. Featuring off-road suspension tuning with skid plates, hill descent control, and the choice of gas or Duramax turbo-diesel power, it’s as capable on rough tracks as it is with a trailer in tow. The dual-rear-wheel configuration ensures stability and control, even when the going gets tough.
DENALI
The Sierra 3500 HD Denali DRW brings premium comfort and style to serious heavy-duty performance. Chrome accents, advanced driver-assist technology, and high-end interior materials set it apart, while available Duramax power and dual rear wheels deliver exceptional towing stability. It’s the perfect balance of luxury and strength, tailored for those who demand both.
DENALI ULTIMATE
The pinnacle of heavy-duty luxury, the Sierra 3500 HD Denali Ultimate DRW combines cutting-edge technology with uncompromising power.
