Description
If you’re searching for a GVM upgrade in Victoria, you’re probably already aware of how quickly a vehicle can hit its weight limit—especially after adding aftermarket accessories, gear, or even with a few mates in the car. Whether you’re a tradies with tools in the tray, a 4WD enthusiast with camping gear piled high, or towing a caravan for a long-haul adventure, understanding and managing your Gross Vehicle Mass (GVM) is critical.
Our goal at TJM Bendigo is to keep you road-ready, safe, and in compliance. With our engineer-certified GVM upgrades, you can legally and confidently increase your vehicle’s capacity—protecting your investment and avoiding hefty fines.
What is GVM?
The maximum weight that your car is legally permitted to carry when fully loaded is known as its gross vehicle mass, or GVM. This includes:
- The car’s actual weight, or curb weight
- Fuel and fluids
- Driver and passengers
- Accessories like bull bars, trays, winches
- Tools, gear, and cargo
Every vehicle sold in Australia has a manufacturer-assigned GVM as part of its Australian Design Rule (ADR) compliance. This figure is not random—it’s calculated based on the strength of the chassis, axles, suspension, and braking systems.
Why You Might Already Be Overweight
Let’s say you own a dual-cab 4WD. On paper, your GVM might be 3,000 kg. Here’s how quickly that gets eaten up:
- Vehicle curb weight: 2,200 kg
- Two adults and gear: 200–300 kg
- Steel bull bar: 60–80 kg
- Steel tray: 150–200 kg
- Roof rack & recovery gear: 50–100 kg
- Dual battery system: 40 kg
- Drawers, fridge, canopy, and tools: 200–400 kg
Just like that, you’re approaching—or exceeding—your GVM.
Risks of Exceeding Your GVM
Driving an overloaded vehicle is more than a mechanical concern—it’s a legal and insurance nightmare. Here’s what can go wrong if you’re over GVM:
- Increased stopping distance and poor braking
- Premature suspension and brake wear
- Type blowouts due to excessive load
- Loss of insurance coverage in an accident
- Police fines and defect notices
- Failure to pass roadworthy inspections
In short, it is costly, risky, and preventable to overload your car.
What is a GVM Upgrade?
A professionally designed modification known as a GVM Upgrade raises the maximum weight that your car is legally permitted to transport. This isn’t just a suspension lift—it’s a certified change to your vehicle’s specifications, and it must be installed by an authorized workshop like TJMBendigo.
It typically involves:
- Heavy-duty suspension upgrades (springs, shocks, bushes)
- Engineering certification and compliance paperwork
- Modification plate fitted to your vehicle
- Updated documentation for VicRoads registration and insurance
When Should You Consider a GVM Upgrade?
If you fit into any of the categories below, a GVM Upgrade in Victoria should be on your radar:
- You’ve added multiple accessories (bull bars, steel trays, winches, roof racks)
- You frequently carry bulky equipment, goods, or people
- You pull a boat, camper trailer or caravan
- You’re converting a vehicle for work or off-road touring
- In order to ensure compliance and avoid expensive penalties

Typically, you can expect to invest between $3,000 and $7,000 for a fully certified GVM upgrade. While this might seem like a substantial outlay, it’s far cheaper than paying for it. In Victoria, the cost of a GVM update might change based on:
