GVM and GCM Upgrade

All information below is relevant to Victorian regulations.

Download our GVM and GCM guide.

Can you I upgrade my GVM Post Rego?

Yes, GVM upgrades can be done both pre and post rego.

Can I upgrade my GCM Post Rego?

No, unless its a 6×6 conversion. To upgrade your GCM it must be done pre registration. GCM upgrades are available on 6×6 conversions as the vehicle is reclassified.

Can I go a 4″ lift and 35’s?

Only if it is pre registration. You can go to a maximum of a 2″ lift and 33’s post registration.

How do I upgrade my BTC?

Upgrading your BTC depends on the kit you use. The 4495 kit and the 6×6 conversion introduce a new rear chassis which is designed to be able to tow loads up to 4000kg with the 4495 GVM upgrades and 4500kg in the 5800 GVM 6×6 conversion. On a 79 series you must upgrade your brake booster and transmission upgrades are also required, this ranges from an upgraded heavy duty clutch to an auto conversion depending on the requirements. These are included in the 4495 kits apart from the auto conversion which is only required for a 5800 GVM. Power upgrades are recommended but not necessary.

Which one do I need?

This depends on what you are planning on using your vehicle for. Do you need the extra GVM or GCM? Do you need more space for a bigger tray and canopy to fit all your gear? Do you want more comfort and better on-road handling?

What are the benefits of a coil conversion?

The main benefit of a coil conversion is the heightened comfort and GVM upgrade. All JMACX Coil Conversion kits incorporate track correction vastly improving the handling of the vehicle.

At what point do I need a heavy vehicle licence?

A heavy vehicle licence is required for vehicles with a 4500 GVM and up.
