West Coast Suspension is authorised under Federal approval number 47230 to supply and fit a GVM suspension upgrade for the Toyota 78/79 Series Land Cruiser Cab Chassis to 3900kg GVM. This enables the operator to legally carry 500-600kg over the factory stipulated GVM.
This GVM upgrade has been ESC tested by Bosch Australia and complies with the ADR 35-05 “Sine with Dwell” requirements and fully certified under RVCS (Road Vehicle Certification System) by the federal Dept. of Infrastructure and Regional Development.
This kit can be fitted to licenced vehicles under the WA state based type approval (TA) system.

Each GVM suspension upgrade is issued with a vehicle compliance plate for TA, fitted next to the OEM compliance plate, stating vehicle particulars and approval number.
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).
