Smarter Load Solutions
When you exceed your vehicle's GVM—even slightly—you risk fines, insurance issues, and unsafe handling. A GVM upgrade gives your vehicle a higher legal load limit, which is ideal for drivers who tow heavy trailers, carry tools and equipment, or travel fully loaded across long distances.
Combined with suspension upgrades, you’ll get better stability, smoother ride quality, and improved braking and steering under load. Whether you're driving a single cab ute or a dual cab touring rig, getting the suspension right transforms how your vehicle performs on and off the road.

Upgrades are typically customised to your specific vehicle, including coil and leaf spring replacement, shock absorbers, and brake improvements if required. It’s not just about comfort—it’s about legal safety and long-term reliability. If your vehicle’s struggling under pressure, it's time for a proper solution.
What is a GVM upgrade and why do I need one?
A GVM (Gross Vehicle Mass) upgrade increases the maximum legal weight your vehicle can carry, including passengers, accessories, cargo, and fuel. It’s especially useful for tradespeople, 4WD tourers, or anyone carrying loads regularly. Factory load limits are often too low for modified or working vehicles, and exceeding them can lead to fines, voided insurance, and poor handling. A certified GVM upgrade makes your setup legal and safer, ensuring your suspension and chassis are rated for the job.
Can I drive my vehicle immediately after a GVM upgrade?
Yes, but only after the upgrade has been certified and approved by the relevant authority (such as a state transport department). In most cases, a compliance plate or documentation will be added to your vehicle as proof of the upgrade. This is essential for insurance and registration purposes. The process is typically handled by the installer and ensures you’re driving legally under the new load rating.
Do suspension upgrades improve towing performance?
Absolutely. Suspension upgrades increase load handling and stability, reduce sagging at the rear, and improve ride quality—especially when towing trailers, caravans, or boats. They also help distribute weight more evenly, which enhances braking, steering, and tyre wear. A suspension upgrade can include upgraded springs, shocks, and bushings to better support your vehicle's specific load needs.
