GVM Upgrades

Transmod offers assessment and certification for vehicle Gross Vehicle Mass (GVM) upgrades. This service is available for most four wheel drives and utes. Both Federal Second Stage Manufacturer (SSM) systems and certification of custom/existing upgrades are catered for.

We have tested and certified hundreds GVM upgrade variations and this experience helps ensure you will get a safe, legal and cost-effective solution. The resulting GVM upgrade certification is valid Australia wide, linked to Queensland registration using modification code LS11.

We’re not an agent for any suspension companies so you can be assured of unbiased advice to help you identify the best GVM solution for you. When you contact Transmod you will talk with a qualified mechanical engineer. Some of our GVM solutions can fill the gap in the market for tow-vehicles owners wanting to offset their trailer’s ball weight with an intermediate rating upgrade. A certified GVM upgrade can be achieved without increased ride height and reduced ride quality associated with high GVM weight ratings.

We can also provide GVM upgrade solutions for older and imported vehicles that don’t have pre-approved upgrade kits. In some cases, Transmod can even help with revisions previously certified GVM upgrades.

For businesses, Transmod can provide GVM upgrade design packages under LS11 suitable for certification under modification code LS15.
