Second Stage Manufactured (SSM) GVM Upgrades
West Coast Suspension is authorised to supply and fit Second Stage Manufactured (SSM) GVM suspension upgrades for many of today’s popular vehicles. This enables the operator to legally carry up to 600kg over the factory stipulated GVM.
Each kit has been fully certified under RVCS (Road Vehicle Certification System) by the federal Dept. of Infrastructure and Regional Development.
Each GVM suspension upgrade is issued with a silver or green modification compliance plate fitted next to the OEM compliance plate, stating vehicle particulars and approval number issued as Second Stage Manufacture. The suspension modification and fixing of the silver modification plate must be done prior to any other modifications and must be done prior to the vehicle being licensed.
