Isuzu RT D-Max 3300kg GVM Upgrade

West Coast Suspension is authorized under Federal approval number 49113 to supply and fit a GVM suspension upgrade for the Isuzu D-Max to 3300kg GVM. This enables the operator to legally carry 150kg over the factory stipulated GVM.

This GVM upgrade is fully certified under RVCS (Road Vehicle Certification System) by the federal Dept. of Infrastructure and Regional Development. 

This kit can be fitted to licenced vehicles under the WA state based type approval (TA) system.

Each GVM suspension upgrade is issued with 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).

Please be aware that these kits must be fitted by a WCS approved fitter/manufacturing facility.
