The Isuzu D-Max is commonly set up for touring or work with trays, canopies, accessories and towing loads. These additions can quickly reduce available payload and limit both carrying and towing capacity.
This 3695kg GVM upgrade with 6200kg GCM is suited to vehicles carrying moderate constant load. It’s a practical option for touring and work setups that need increased payload while maintaining stable and predictable handling.
Note: GCM revision is not available with post rego upgrades

Compliance
This is an ADR-compliant and federally approved GVM upgrade. For federal approval, the kit must be installed prior to first registration. This pathway suits new vehicles and allows for a certified GVM & GCM increase from day one.
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: GCM increase is NOT available post registration for this vehicle. 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.
