Chevrolet Silverado 2500 HD buyers in Australia will soon be able to order a factory-backed 5th wheel towing setup, with GMSV announcing a new Genuine 5th Wheel Hitch option for MY26 Silverado 2500 HD NB2 variants.

Available on vehicles built from Q3 2026, the option increases maximum braked towing capacity to 8000kg. Customers will be able to choose between a 50mm Pin Coupling or a three-inch Gooseball as part of two factory towing solutions. Pricing is set at $20,000 for the 50mm Pin Coupling option and $18,000 for the 3-inch Gooseball setup.

Both 5th Wheel Hitch options incorporate a factory air brake system, along with a range of towing-specific hardware and vehicle upgrades. These include a chassis structure and bed attachment plate, trailer connectors mounted at the front of the truck bed, trailer brake airlines, and additional interior controls and warning lights.

The 5th Wheel Hitch package will be fitted locally during the Silverado’s right-hand-drive remanufacturing process, rather than installed after delivery.

“Silverado 2500 HD customers often have serious towing requirements, and they want a solution that gives them greater confidence, capability and flexibility,” said Jess Bala, Managing Director at GM Australia and New Zealand. “The new Genuine 5th Wheel Hitch option expands what Silverado 2500 can already do for those customers, while preserving the premium refinement and heavy-duty performance they expect from the vehicle.”

Bala added, “The choice of 50mm Pin Coupling or 3-inch Gooseball means customers can select the setup that best matches the trailers they tow, while the factory-integrated air brake system adds another layer of confidence for larger combinations. It is a practical, purpose-built solution that makes the Silverado 2500 HD even more capable for customers with specialised towing needs.”

The Genuine 5th Wheel Hitch option will form part of the vehicle as supplied and will be covered under GM’s five-year, unlimited-kilometre warranty.

The new towing package is available exclusively on NB2-certified Silverado 2500 HD variants. As an NB2-certified vehicle, licensing requirements apply, and prospective owners are advised to check the relevant requirements with their State Roads Authority.

So what does this actually mean?

This option turns the Silverado 2500 HD into a more serious heavy-towing setup, closer to US-style 5th-wheel or gooseneck towing than a standard towball arrangement.

The key change is how the trailer connects to the truck: The load is transferred through a bed-mounted coupling (either a pin coupling or gooseball) that sits over or near the rear axle, rather than from a rear hitch. This generally improves stability and control when hauling very large trailers.

The factory air brake system and added trailer brake components mean the braking setup is integrated into the vehicle rather than relying on aftermarket solutions, giving more consistent braking behaviour when towing heavier, more complex trailer combinations.

The chassis structure and bed-mounted attachment plate provide the physical reinforcement needed to handle that type of load, while the additional connectors, brake airlines, and in-cabin controls and warning lights make setup, monitoring and operation easier from the driver’s seat.
