Toyota Gen 8 Hilux 3300kg or 3500kg GVM Upgrade

West Coast Suspension is authorized under Federal approval number 47898 to supply and fit a GVM suspension upgrade for the Toyota Gen 8 Hilux to 3300 or 3500kg GVM. This enables the operator to legally carry 300-500kg over the factory stipulated GVM.

Please note: To obtain the 3500kg upgrade, the tyre load rating must be no less than “110” with a speed rating not less than “S”

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 pre-licenced vehicles under the federal second stage manufacture (SSM) system or licenced vehicles under the WA 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.
