The 79 Series is often built for heavy-duty use, with trays, canopies, service bodies and towing loads placing sustained demand on the vehicle. Factory payload limits are commonly exceeded in these applications.
This 4200kg GVM upgrade is designed for higher constant load vehicles, including work and touring setups carrying significant weight. The matched suspension package is selected to maintain control and durability under load, not just increase the GVM figure. This upgrade also allows for an increase in GCM where applicable, supporting higher combined vehicle and trailer weights.

For registered vehicles, the upgrade must be certified by an Authorised Inspection Station. The vehicle must be in roadworthy condition and presented for inspection following installation. Our pricing covers the full process, including the modification application, inspection, and final approval permit.
Note: The Western Australian Government has indicated that post registration GCM upgrade for this vehicle may be approved in future. However, no implementation date has been confirmed. Lovells continues to work closely with the Department of Transport to progress this approval.
General Usage
This upgrade is designed for vehicles carrying increased constant loads. Ride quality may be firmer when unladen. The GVM upgrade kit must be installed by Ultimate 4WD, an approved Lovells GVM certifier, to ensure full compliance and a legally recognised upgrade.
