Description
When you are on the trail, looking at the search for GVM upgrade in Victoria, you are most likely to already know how fast a vehicle can quickly reach its weight limit and that is especially after installing aftermarket accessories, gear, or even with a few mates in the vehicle. You might have a tool-laden tray as a tradie or piled-high camping gear as a 4WD aficionado, or want to tow a caravan on a long-haul family holiday; but Gross Vehicle Mass (GVM) is important to know and understand.
Here at TJM Bendigo, we want to ensure that you would be road-worthy, safe, and compliant. By having your own, engineer-certified GVM upgrades through us, you are allowed to be on the safe side of the law and safely and legally increase the capacity of your vehicle to protect the investment you have made and save yourself a big fine.
What Is GVM Upgrade? & Why You May Need It?
GVM is shortened to Gross Vehicle Mass; this is the highest legal weight that your vehicle can carry without breaking the law such as the vehicle weight, each auto manufacturer gives a legal GVM for every vehicle. It is a crime to cross it and it can also affect your insurance, guarantee and safety on the road.
Think of it like this:
Kerb Weight (empty vehicle)
- passengers
- fuel
- fridge, drawers, canopy, tools, etc.
= Your actual weight
→ If that’s over your GVM, you need an upgrade.
Common Reasons to Upgrade Your GVM
These are the most common scenarios when drivers require an upgrade of the GVM:
- Towing Caravans or Trailers
Adding a towball load to your rear axle puts more stress on suspension and affects GVM. - Fitting Canopies or Toolboxes
Tradies loading up drawers, shelves, compressors, and heavy tools easily exceed the limit. - Touring & Off-Grid Setups
Extra batteries, solar, water tanks, roof racks, awnings—that stuff all counts towards your total weight. - Commercial Use
Racks, signage, cargo, ladders, or materials increase load on a daily basis.
If this describes your setup, then a certified GVM upgrade is the answer, which will keep you compliant and safe while under load.
Benefits of a GVM Upgrade in Victoria
GVM upgrades aren’t just about numbers—they improve performance, safety, and compliance. Here’s why you should consider it:
Stay Legal on Victorian Roads
Overloaded vehicles are illegal under VicRoads and national road laws.By having a certified GMV increase, you can rest easy as to being compliant, no fines, and certainly no vehicle defect.
Protect Your Insurance & Warranty
Insurers can turn down claims if your vehicle weighs greater than its GVM. An upgrade keeps your coverage valid and your setup recognised legally.
Improved Safety & Braking
Improved suspension makes it easier to deal with additional weight. You will have increased stability, better braking and safe towing during all conditions.
Peace of Mind
Be it driving around the outback or down to work, you will feel that your car is at its max capacity and that it is able to do the work.
Increase Vehicle Value
Buyers will pay more for a properly engineered and certified GVM upgrade—especially for popular 4WDs used for towing or touring.
Pre-Registration vs Post-Registration GVM Upgrades
There are two ways to upgrade your GVM—either before your vehicle is registered (pre-rego) or after it’s already on the road (post-rego).
| Type | When Done | Engineer Certificate Required? | |
| Pre-Registration | Before first rego (brand new vehicle) | Usually included by the kit provider | |
| Post-Registration | After rego (used vehicle or already owned) | Yes – VASS engineer sign-off needed |
Which Option is Better?
Pre-rego upgrades are generally cheaper, faster, and more streamlined—especially if done at the dealership or soon after purchase.
Post-rego requires more paperwork, inspections, certification by a VASS engineer, and VicRoads documentation
