From Offroad Industries

At TMWA, we don’t do things by halves. We specialise in American trucks and hardcore 4x4s, and when it comes to GVM upgrades, we’ve partnered with the best to bring you the highest standard of engineering. We are now installing the Offroad Industries GVM system, engineered for serious rigs like Chevrolet and RAM, and we’ve also got you covered for your Land Cruiser and Tundra.

Our GVM upgrades are engineered to boost your vehicle’s Gross Vehicle Mass, giving you the payload and towing capacity you need to get the job done—whether that’s for work or for play. This is a high-quality, American-made system from industry leaders Fox and BDS, ensuring your rig is built to handle anything you throw at it.

We don’t just bolt on parts and hope for the best. Every Offroad Industries GVM upgrade we install is put through a rigorous testing process that includes ADR brake assessments and individual stress analyses. This isn’t just about meeting Australian Design Rules; it’s about exceeding them. We use advanced strength analysis on both the factory parts and the ORI system components to ensure every upgrade is a true improvement in safety and performance.

The result is a GVM upgrade that gives you better handling, increased ground clearance, and the confidence to load up your ute or 4×4 for any adventure. This system often includes a mix of lift kits, suspension upgrades, and specifically engineered leaf packs and coil springs designed to handle increased rear axle loads without a fuss.

FAQs

Why choose an Offroad Industries GVM upgrade installed by TMWA?

Simple. We’ve partnered with Offroad Industries because they’re the real deal. Their systems use top-shelf, USA-made suspension components from Fox and BDS, engineered to an exceptional standard. We don’t just install it; we ensure it’s the perfect fit for your rig, whether you’re running a Silverado, F Truck, Ram or Toyota. It’s an upgrade built to perform.

How do Fox and BDS components improve my vehicle's performance?

These aren’t just generic parts. The lift kits, shocks, and coil-overs from Fox and BDS are built for brute force. They give you the ground clearance you need, handle better on rough terrain, and provide the support required for heavy payloads. This is about boosting your rig’s capabilities, not just its looks.

What's involved in the GVM testing process?

We’re not guessing here. The Offroad Industries GVM system is subjected to a rigorous testing process that goes beyond the minimum requirements. It includes ADR (Australian Design Rules) brake assessments and individual stress analyses to guarantee your vehicle is safe under full load. They use detailed computer modelling and real-world track testing—it’s a proven process.

How does a GVM upgrade improve towing and payload capacity?

An Offroad Industries GVM upgrade is engineered to legally increase your vehicle’s load capacity. By reinforcing the suspension and other key components, it allows you to safely carry heavier payloads and tow bigger trailers, so you can get the job done without compromise.

What is the role of the ORI Leaf Pack?

The ORI Leaf Pack is a key part of the system for utes. It’s specifically designed to support increased rear axle loads, which means your vehicle maintains its proper ride height and stability even when fully loaded. It’s about providing strength and reliability where you need it most.
