What upgrades help modernise older GMC 2500/3500 trucks from 2011–2019?

GMC trucks are an investment, and if you’re looking to get more power and control without needing to purchase a whole new vehicle, Offroad Industries’ range can help. For one, upgrading your suspension or considering a GVM upgrade is always a top choice. Not only do you get greater ground clearance, but these options will also help you haul more, get greater stability, and give you the ability to handle the toughest terrain Australia can throw your way. 

To customise the look of your earlier model, you can also consider adding upgrades that serve a dual purpose. Additions like fender flares to help protect your vehicle, and custom wheels to match improved suspension, are both popular options that add a new look and feel to your driving experience. These GMC parts and accessories help bridge the gap to newer models - without losing any of its original strength and appeal. 

How do Fox or BDS suspension systems improve handling and load capacity for GMC trucks?

Heavy-duty trucks like the Sierra 2500/3500 are built to haul and tow everything from your tools to your trailer, but if you want to boost ride quality and handling while you’re pulling heavy loads, suspension systems from the likes of Fox Suspension are ideal. 

They feature advanced and heavy-duty components that have been torture tested to provide a smoother, more controlled ride - especially under load or on rough surfaces. They also boost your truck’s load capacity and off-road confidence, making it easy to get where you want to go, with all your gear safely on board.


What are the options for long-range fuel tanks to extend touring range on GMC trucks?

When the road calls you far from home, or you’re heading off into uncharted territory and want to make sure you have plenty of fuel on deck, GMC long-range fuel tanks are an indispensable upgrade. They’re made from durable, corrosion-resistant materials and are designed for straightforward installation in Australian-spec vehicles. Long range fuel tanks increase your driving range, while also giving you the confidence you need to explore further between refuelling stops - making them ideal for touring, towing, and outback adventures. 


Are GMC aftermarket parts from ORI designed to handle Australian off-road conditions?

Yes, they certainly are. We stock GMC 2500 and 3500 accessories and upgrades that are built tough, with your truck model in mind. They’re made from resilient materials, with tough and resilient designs that can handle everything from cold and rugged mountain ranges to the hot and salty conditions of the coast. From suspension and roller shutters to side steps and lighting, every upgrade is selected for durability, performance, and compliance with local requirements.

To get the perfect fit and ensure everything is road-worthy and compliant, we recommend booking in with one of our authorised installers once you’ve received your parts. This ensures your GMC not only looks the part but can tackle anything Australia throws its way.
