What is a GVM?

GVM stands for Gross Vehicle Mass (also called Gross Vehicle Weight in some regions). It refers to the maximum legal weight of a vehicle when fully loaded, including:

• The vehicle's own weight
   
• Fuel and fluids
   
• Passengers
   
• Cargo
   
• Accessories or modifications (e.g., bull bars, toolboxes)

 A GVM (Gross Vehicle Mass) upgrade can offer significant benefits, especially if you regularly carry heavy loads or modify your vehicle. Here’s a breakdown of the key benefits:

• Lets you legally carry more weight (cargo, tools, equipment, passengers).
   
• Ideal for tradespeople, campers, tourers, or anyone carrying heavy loads
   

• Avoid fines or defects for driving overweight.
   
• Ensures your vehicle remains roadworthy and covered by insurance.
   
• Essential if you've added heavy accessories like bull bars, winches, long-range fuel tanks, or drawer systems.
   

• Upgraded suspension systems provide better handling under load.
   
• Reduced risk of brake failure, poor steering, or tire blowouts.
   
• Helps maintain stability, especially when towing or driving off-road.
   

• A GVM upgrade often includes suspension enhancements that help your vehicle handle weight more evenly, reducing rear sag and improving balance.
   

• Stronger suspension and increased clearance can improve off-road capability.
   
• Useful for remote travel where you're fully loaded with supplies, water, fuel, and recovery gear.
   

• GVM upgrades can help ensure your GCM (Gross Combined Mass) remains compliant when towing.
   
• Prevents overloading when combining trailer weight with a loaded vehicle.

GVM upgrades must be engineered and certified to be legal. There are two main types:

• Pre-registration upgrade (done before first registration, no additional paperwork needed)
   
• Post-registration upgrade (requires inspection and certification by an authorized engineer)
