GVM Upgrades
In Busselton
Loading up for a big trip? There's a good chance you're already over your Gross Vehicle Mass - and most people don't know until something goes wrong. We're the only certified GVM installers in Busselton.
What Is A GVM Upgrade?
A Gross Vehicle Mass (GVM) upgrade increases the maximum allowable weight your vehicle can legally carry - the vehicle itself, passengers, fuel and cargo. Overloading causes braking problems, suspension failure and legal fines. If your vehicle works hard, a GVM upgrade keeps you safe and on the right side of the law.
It's worth considering if you are:
- A tradesperson carrying heavy tools and equipment
- Towing a caravan or trailer regularly
- An off-road tourer carrying extra supplies for the big lap
- Running vehicles that transport goods long distances
Loading Up For A Big Trip? You Might Already Be Over Your GVM
Many owners are over their Gross Vehicle Mass without knowing it. Use our quick guide to work out your vehicle's GVM and whether an upgrade is right for you.
The GVM Certification Process
Upgrading your GVM is more than fitting new suspension. It is a detailed process that ensures your vehicle is safe, legal and roadworthy after the modification.
Initial Consultation
We assess your vehicle and your specific load requirements, then recommend the right kit and shock options for how you use it.
Suspension Installation
Our experienced technicians install the appropriate Dobinsons suspension kit to safely increase your vehicle's load-carrying capacity.
Certification
We certify the vehicle against Australian Design Rules (ADR), so you drive away with the paperwork done and the capacity to carry what you actually need to carry.
Dobinsons GVM Upgrades
Dobinsons kits are designed and tested specifically for Australian conditions - not repurposed from European touring specs. The springs, shocks and components we fit are built for WA roads, corrugated station tracks and heavy tow loads. That's why we recommend them.
- Certified by the Department of Infrastructure and Transport
- Improved handling, stability and safety under load
- Certified across the most popular WA touring platforms - Ranger, Hilux, Prado, LandCruiser and more
