GVM Upgrades

If you’re looking to kit out your 4WD with all the aftermarket gear you need, chances are you’ll need a GVM upgrade to stay on the right side of the law.

ATOC Auto are 4WD enthusiasts, offering GVM upgrades that will ensure the overall safety of your 4WD is maintained so you can enjoy your 4WDing while staying within the legal limits.

GVM, or Gross Vehicle Mass, is specified by the OE manufacturer. It’s the maximum your vehicle can legally weigh when fully loaded. Tools, toolboxes, aftermarket accessories, and even your passengers all add up and before you know it, you’ve exceeded your GVM. Exceeding the GVM is illegal and poses a safety concern.

We offer engineered GVM upgrade packages to suit a wide range of applications and vehicles, including, but not limited to Toyota Hilux, Landcruiser 70, 100, 105 & 200 series, Prado GDJ150 and Nissan GU & Y62 Patrols. All our work is completed and certified onsite in our workshop, located at 13 Temple Rd, Belgrave South.

All of our GVM upgrades come with heavy-duty Koni shock absorbers that are valved to suit your vehicle (except Y62 GVM upgrades).

Using our industry knowledge and experience we’ll provide your vehicle with a purpose designed solution of shock absorbers, springs, and other quality suspension components to ensure your 4WD is fit for purpose.
