What is a GVM Upgrade?
- GVM (Gross Vehicle Mass) is a rating set by the original manufacturer and refers to the legal maximum total weight of the vehicle. This includes the weight of the vehicle itself, the bull bar, fuel, water tank, cargo, etc and includes the driver and passengers. Think of it as the maximum load your vehicle can safely carry.
- The GVM also determines the imparted Tow Ball Mass when towing and Rated Axle Capacity, which limits how much weight should be distributed to each vehicle.
- A GVM Upgrade includes upgraded suspension components to increase a vehicle’s carrying capacity and ensure safety and performance when carrying heavier loads.
Why is a GVM Upgrade Important?
- Safety > Exceeding your vehicle’s GVM can compromise its handling, braking, and overall safety.
- Legality > Driving a vehicle with an overloaded GVM can lead to fines and invalidation of your insurance.
- Vehicle Performance > Overloading can strain your vehicle’s components, leading to premature wear and tear.
Why Upgrade Your GVM?
- Increased Payload Capacity > Carry more camping gear, recovery equipment, or heavy trailers without compromising your vehicle’s stability or performance.
- Improved Off-Road Capability > A higher GVM enables you to tackle more challenging terrain with confidence, knowing your vehicle can handle the weight of additional accessories and modifications.
- Enhanced Safety > By ensuring your vehicle is legally equipped to handle the loads you carry, you’re prioritizing safety both on and off the road.
- Legality > Driving a vehicle with an overloaded GVM can lead to fines and invalidation of your insurance.
What is Post Registration?
- Post-registration is when the modifications or additions are performed after the vehicle has been registered.
- Post-registration fitment will require the additional cost of an engineer’s inspection and sign-off of the upgrade when it is completed.
- Individual states have their own approval process, where an authorised Automotive Engineer inspects and tests the vehicle before issuing a compliance certificate.
