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).
