However, when owners fit essential Outback accessories—such as steel bullbars, electric winches, roof platforms, dual battery systems, drawer modules, and heavy tow ball loads—the vehicle rapidly approaches its factory Gross Vehicle Mass (GVM) limit. Exceeding your legal GVM compromises handling and braking, voids vehicle insurance, and risks heavy road authority penalties. The Toyota Prado 250 JMACX 3800kg GVM Upgrade Kit (Pre-Registration) provides the ultimate legally certified solution. Engineered by JMACX and fitted by Hunter Mechanical before initial vehicle registration, this Federal Second Stage Manufacture (SSM) approved kit elevates your GVM to 3800kg while maintaining a full 3500kg braked towing capacity.\u003c\/p\u003e\n\u003cp\u003eWhy Choose Hunter Mechanical\u003cbr\u003eHunter Mechanical is Western Australia's leading 4WD performance and suspension facility, with state-of-the-art workshops in Perth, Rockingham, and Karratha.
