Toyota 78/79 Series LandCruiser J7 4200kg GVM Upgrade

West Coast Suspension is authorised under Federal approval number VTA-061452 to supply and fit a GVM suspension upgrade for the Toyota 78-79 Series LandCruiser J7 to 4200kg GVM. This enables the operator to legally carry 690kg over the factory stipulated GVM.

Please note: To obtain the 4200kg upgrade, the tyres fitted to the vehicle must be 225/95R16C or 265/70R16LT with a load rating no less than “117” and a speed rating not less than “R”

This kit has been tested by the Auto Innovation Centre and fully certified under RVSA (Road Vehicle Standards Act 2018) by the federal Department of Infrastructure, Transport, Regional Development, Communications and the Arts under the ROVER system.

This GVM upgrade has also had FEA analysis on OEM suspension components such as diff housings to ensure each OEM part retained is up to the task of carrying the extra payload.

This kit can be fitted to pre licenced vehicles under the federal second stage manufacture (SSM) system or licenced vehicles under the state based type approval (TA) system.

Each GVM suspension upgrade is issued with a SVI (Secure Vehicle Identification) sticker for SSM or a vehicle compliance plate for TA, fitted next to the OEM compliance plate, stating vehicle particulars and approval number.

SSM modification and fixing of the SVI sticker must be done prior to any other modifications and must be done prior to the vehicle being licensed.

For vehicles that have already been licenced, the GVM certification process varies depending on state or territory. The vehicle may be need to be inspected by an authorised Automotive Engineer to comply with that state or territory’s GVM compliance requirements. 

WCS GVM upgrades only increase the Gross Vehicle Mass (GVM).  They do NOT increase the Gross Combined Mass (GCM) or Braked Towing Capacity (BTC).

Please be aware that these kits must be fitted by a WCS approved fitter/manufacturing facility.
