LoadSafe – New Zealand’s home of Gross Vehicle Mass (GVM) Increase and VB Air Suspension

Hello, and Welcome to LoadSafe New Zealand – New Zealand’s specialist for increasing Gross Vehicle Masses (GVM). Or in other words, increasing the amount of ‘payload’ your vehicle can carry. What is ‘payload’? It is the difference between GVM (maximum legal weight) and Tare weight.

LoadSafe NZ has partnered with a leading European Vehicle Consultancy to allow vehicles like Motorhomes, to be re-rated to a higher Gross Vehicle Mass (GVM), often with increased axle weights.

We offer solutions for Fiat Ducato, Peugeot Boxer, Citroën Relay, Ford Transits, Mercedes-Benz Sprinters, Volkswagen Crafter, including those fitted with the ALKO chassis, and many more.

LoadSafe also supplies world-class VB-AirSuspension systems from the Netherlands. VB-AirSuspension manufactures air suspension systems ranging from helper coil springs to complete retrofit Full Air suspension units. They TÜV type-approve all suspensions for each specific vehicle type, ensuring your ongoing safety.

Is your Motorhome or Light Commercial Vehicle overweight?

That is, exceeding its Gross Vehicle Mass (GVM) and / or allowable axle(s) weight limit. If you’re unsure, you’ve come to the right place.

Don’t wait until you discover your vehicle is overweight and end up parked on the roadside unloading before you can continue—or worse, paying an expensive fine. Overloading is dangerous, and your insurance company may reject your claim if you operate your vehicle outside legal compliance.

Operating overweight directly affects safety and comfort. Many drivers overload because they don’t know their vehicle’s load (payload) capacity. Often, they pack without realizing the consequences.

When we re-rate your vehicle, we install additional suspension components to support the extra weight, making it safer at higher loads. The advantages include:

  • Improved safety
  • Enhanced ride comfort
  • Increased payload
  • Upgraded axle loads

Do you know your weights? Are you running over weight?

(If you don’t know your legal maximums, read our page on chassis rating plates)

Do you need more Payload?

Do you want to be safe?

If so, check the Vehicles menu above to see the models we can Up-Rate. We continue to add more vehicles in the future.

To re-rate your vehicle, we need specific information from you. Please complete the form at the link below and email it to us with the requested photos and weights. We assess each vehicle individually against our approvals database to determine the maximum Gross Vehicle Mass (GVM) possible.

All axle components—axle, suspension, rims, and tyres—must carry a sufficient rating for the higher allowable weights. The final axle rating depends on the lowest-rated component of the four. To achieve the best outcome, you may need to replace rims and tyres with higher-rated items. Contact us to discuss your options.

Important: if your GVM increases from 3500 kg or less, to over 3500 kg, your vehicle will require COF inspections in future.
