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. 

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).
