At Northern Springworks, we supply EFS GVM (Gross Vehicle Mass) upgrade kits to help you legally carry more without compromising safety or compliance. Whether you’re towing, touring, or just running out of payload on a daily basis, an EFS GVM upgrade could be exactly what your vehicle needs.
We are an authorised supplier ofEFS Suspension, one of Australia’s most trusted names in 4×4 suspension and GVM solutions. If you’re constantly pushing your vehicle to the limit with tools, equipment, accessories or towing loads, upgrading your GVM is not just a smart move — it’s a legal requirement.
What Is a GVM Upgrade?
GVM refers to the maximum allowable weight of a fully loaded vehicle, including passengers, fuel, tools, canopy, bull bars, and anything else onboard.
Many modern 4WDs and utes quickly exceed their GVM once you factor in accessories and gear. This can lead to:
Insurance issues
Legal fines
Reduced braking performance
Premature wear and tear
An EFS GVM Upgrade Kit increases your vehicle’s legal load capacity by replacing factory suspension components with upgraded, heavy-duty alternatives. These kits are engineered, tested, and certified to meet national compliance standards.
Why Choose EFS GVM Upgrades?
EFS (Enhanced 4WD Suspension) is a proudly Australian-owned brand, known for tough, reliable suspension systems built for our harsh conditions. Every EFS GVM upgrade kit is:
Certified & ADR-compliant
Designed for Australian conditions
Matched to your specific vehicle make/model
Tested for on-road and off-road performance
Whether you’re upgrading a Toyota Hilux, Ford Ranger, Isuzu D-MAX or LandCruiser, there’s a tailored EFS GVM solution ready to go.
Run a business that relies on carrying constant loads
Are installing a canopy, dual battery, fridge or water tanks
A standard ute or 4WD may have a GVM of 3,000kg or less. Once you add passengers and gear, you can easily exceed this. An EFS upgrade can legally raise this limit (e.g. up to 3,500kg+), depending on your vehicle model and kit chosen.
