West Coast Suspensions is a federally approved second stage manufacturer (SSM) and are able to supply and fit GVM upgrades to pre-licenced vehicles.  WCS can also supply and fit GVM upgrades to licenced vehicles under the WA state based type approval (TA) system.

Each kit has been fully certified under either RVCS or RVSA (Road Vehicle Standards Act 2018) by the federal Department of Infrastructure, Transport, Regional Development, Communications and the Arts.

While testing new GVM upgrades, WCS also have FEA analysis carried out on OEM suspension components such as control arms, knuckles and diff housings to ensure each OEM part retained is up to the task of carrying the extra payload.

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).
