Nissan Y61 Patrol Wagon GVM Upgrade
Get up to an extra 500KG payload – Upgrade your GVM to 3500KG
The Nissan Y61 Patrol Wagon is known for its rugged build and off-road ability, but the factory payload can be restrictive once accessories, camping gear, or towing equipment are added.
Keeping within the manufacturer’s Gross Vehicle Mass (GVM) is difficult when setting up for serious touring or work duties.
Tough Dog Suspension, as a recognised Second Stage Manufacturer (SSM), develops federally certified upgrades to boost your Patrol’s GVM. This lets you carry more weight legally while maintaining compliance and safety.
Each GVM kit is thoroughly tested to ensure ADR compliance is upheld.
Federal approval for GVM upgrades requires strict testing to confirm that the vehicle performs to or above OEM standards with the increased load.
A Tough Dog GVM upgrade ensures your Y61 Patrol continues to handle and brake safely, even at full capacity. Depending on requirements, testing includes:
- Finite Element Analysis (FEA) testing: Confirms axle strength and maximum load limits.
- Brake Testing: Conducted laden, unladen, and with partial failure to comply with ADR35/00.
- ESC Testing: If applicable, ensures the electronic stability control system remains effective or better than factory standard.
The GVM is the maximum permissible weight of a vehicle when fully loaded. With a Tough Dog upgrade, the Nissan Y61 Patrol Wagon can carry more payload without breaching ADRs or safety regulations.
Certification options depend on whether the vehicle is new or already registered:
- Federal Approval: For new vehicles prior to first registration, including an additional compliance plate.
- State Approval: For registered vehicles, approval is achieved using Federal compliance data and inspection by an authorised state engineer.
