Mazda BT-50 (MY21 On) GVM Upgrade
Get up to an extra 600KG payload – Upgrade your GVM to 3450KG
The Mazda BT-50 MY21 On shares its platform with the Isuzu D-MAX, offering a strong base but limited payload once passengers, luggage, and accessories are added.
Staying under the Gross Vehicle Mass (GVM) becomes difficult when fully loaded for work or touring.
Tough Dog Suspension, as a recognised Second Stage Manufacturer (SSM), provides federally certified upgrades to increase your BT-50’s GVM, letting you safely and legally carry more load without risking compliance.
Every Tough Dog GVM kit is rigorously tested to maintain ADR compliance.
Federal approval for GVM upgrades involves strict testing to ensure the Mazda BT-50 performs to or beyond factory specifications.
With a Tough Dog GVM upgrade, your BT-50 will maintain safe handling and braking performance even with heavy loads. Depending on the model, testing includes:
- Finite Element Analysis (FEA) testing: Confirms axle strength and load capacity.
- Brake Testing: Performed laden, unladen, and under partial system failure to meet ADR35/00 requirements.
- ESC Testing: If required, ensures the electronic stability control system performs equal to or better than the factory setup.
The GVM is the maximum allowable vehicle weight when fully loaded. A Tough Dog GVM upgrade increases the Mazda BT-50’s legal carrying capacity while staying compliant with ADRs and safety laws.
Certification is determined by registration status:
- Federal Approval: For new, unregistered vehicles. Supplied with an additional compliance plate.
- State Approval: For already-registered vehicles. Approval is achieved using Federal compliance data with inspection by an authorised state engineer.
