Trusted Dobinsons GVM Facility
Dobinsons GVM Upgrade – Mazda BT-50 (2020 on)
GVM to 3,600 kg · Federally approved · Supplied & fitted at Smeaton Grange
More legal payload for your BT-50
The 2020-on BT-50 shares its underpinnings with the D-Max and has the same payload squeeze once it is kitted out. Dobinsons takes the BT-50 4x4 to 3,600 kg GVM, keeping factory wheels and tyres and the factory GCM.
As an authorised Dobinsons GVM fitter, we replace the factory springs and shocks with a matched, federally approved Dobinsons package. You choose spring rates to suit your accessories and a shock to suit how you drive, and we fit it, update the compliance and send you on your way.
- New GVM: 3,600 kg – 4x4 variants only.
- Towing: GCM stays at the factory figure
- Approval: Pre-rego and post-rego*

Pre-rego or post-rego?
Pre-registration
Fitted before first registration under the federal approval. Your vehicle is recognised Australia-wide for life, and it is usually the simplest and cheapest path if you are buying new.
Post-registration
For vehicles already on the road. An approved signatory certifies the upgrade under NSW rules and your rego is updated. Further charges for state based engineering may apply, and the vehicle may need re-certifying if it moves interstate.
Why Project Overlander
Trusted GVM facility
We fit Dobinsons GVM upgrades in-house at our Smeaton Grange workshop – fitted by our own technicians, not sub-contracted.
Paperwork handled
We organise the compliance plate, certification and rego update, whether your vehicle is new or already on the road.
Build it once
Combine your GVM upgrade with trays, canopies, drawers, long range tanks and 12V from the same workshop, so the whole build is planned around your new payload.
BT-50 GVM FAQs

Are upper control arms included?
They are an optional extra at $1,100 fitted.
What does the price include?
Prices include GST and cover the Dobinsons kit supplied and fitted by an authorised Dobinsons GVM fitter at our Smeaton Grange workshop. Further charges for state based engineering may apply, and load rated wheels and tyres are extra where a kit requires them.
