Toyota 300 Series Landcruiser 3800kg GVM Upgrade

West Coast Suspension is authorised under Federal approval number VTA-063725 to supply and fit a 3800kg GVM upgrade to 300 Series Landcruiser Wagons. This enables the operator to legally carry up to 520kg over the factory stipulated GVM.

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.

Once this kit has been fitted to your Landcruiser, it actually changes the vehicle category from MC to NB1.  This requires fitting of category 6 side indicators and a reverse lamp, supplied with the kit. 

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. 

Variants of the Toyota Landcruiser 300 series covered by this upgrade are: GX, GXL, VX, Sahara. (Sahara ZX & GR Sport variants are currently excluded)

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.
