Why 70 Series GVM Upgrades Can’t Be Done Pre-Rego In 2026

If you’re researching a 70 Series GVM pre-rego upgrade in 2026 and you’ve been told it’s no longer possible - you’re not getting the runaround.

As of 1 November 2025, changes to ADR 80/04 (Euro VI emissions standards) have effectively shut down the federal pre-registration GVM pathway for the Toyota LandCruiser 70 Series.

This Sandy 79 Series had its GVM upgrade completed pre-rego — the process that’s changing from 2026 onward.

This affects all models in the Toyota LandCruiser 70 Series range:

Model	Engine Variants Affected
Toyota LandCruiser 76 Series	2.8L & 4.5L V8
Toyota LandCruiser 78 Series	2.8L & 4.5L V8
Toyota LandCruiser 79 Series	2.8L & 4.5L V8

And no, the GVM manufacturers didn't stopped making kits and no it's not because the 70 Series is illegal.

It comes down to emissions compliance and how federally approved pre-rego GVM upgrades (SSM) are certified in Australia.

The good news? You can still buy a 70 Series and you can still upgrade the GVM. But the pathway has changed. That’s where most of the confusion is, let’s break it down.

SHORT VERSION: 70 SERIES GVM PRE-REGO BLOCKED

You can’t do a 70 Series GVM pre-rego in 2026 because:

• The government introduced stricter Euro VI emissions rules (ADR 80/04).

• The 70 Series hasn’t yet been updated to comply.

• Federal GVM approvals rely on Toyota’s emissions certification.

• Without that updated certification, SSM approval cannot be issued.

WHAT CHANGED WITH THE 70 SERIES GVM UPGRADE PRE-REGO UNDER ADR 80/04?

From 1 November 2025, Australia introduced ADR 80/04, which adopts Euro VI Stage C emissions standards for heavy vehicles over 3.5 tonnes.

The 70 Series falls into that heavy vehicle category. It was only in 2023 Toyota increased the GVM above 3500kg so it didn't have to comply with newer safety regulations.

Euro VI significantly tightens emissions limits. Up to 80% reduction in nitrogen oxides (AKA dirty exhaust gas). This is a federal environmental regulation.

WHY 80/04 STOPS 70 SERIES GVM UPGRADE PRE-REGO APPROVALS

A federally approved pre-rego GVM upgrade is done under the Second Stage Manufacture (SSM) pathway.

For that to be legal:

• The base vehicle must have current federal emissions approval.

• The GVM supplier must reference that approval when issuing their own certification.

• The vehicle must be entered into the RAV (Register of Approved Vehicles) before delivery.

Here’s the problem. Right now, the 70 Series hasn’t been updated to that new emissions standard. It was certified under Euro V. Toyota has said the 70 Series will not achieve Euro VI compliance until mid-2026.

Without that updated approval from Toyota:

• GVM suppliers cannot amend their VTA approvals (like a permission slip)

• New federal SSM certifications cannot be issued.

• Vehicles uploaded to RAV after 1 November 2025 fall under the new emissions laws

That’s the bottleneck.

Strength matters. Upgraded diff housings are often part of a 70 Series GVM upgrade.

ARE POST-REGO 70 SERIES GVM UPGRADES STILL POSSIBLE?

In most cases, yes - a post-rego GVM upgrade is still possible on a 70 Series. It now depends on the GVM manufacturer and a state-based engineer approving the vehicle.

But whether it’s possible depends on a few things:

• The GVM upgrade kit and manufacturer

• The engineer approving the modification

• The state the vehicle is registered in

So the short answer is: it depends.

Some 70 Series vehicles can still be upgraded post-rego, while others may have limitations depending on the setup and approval pathway.

THE BEST WAY TO FIND OUT

If you already own a 70 Series (or you’re about to buy one) the best thing to do is talk to a workshop that deals with GVM upgrades every day, in the state your vehicle is registered in. (If you’re in QLD, call us)

They will look at:

• The year & model (e.g. 2025 79 Series)

• The GVM kit you’re considering (e.g. Tough Dog, Superior Engineering)

• The state you’re registering it in

…and tell you straight away what your options are.

Because with the current rules around the 70 Series, every vehicle needs to be assessed properly before booking a GVM upgrade.

Even the 76 Series wagon can't receive a pre-rego GVM upgrade.

WHAT ABOUT THE V8 70 SERIES?

The V8 has officially reached the end of the road. Since V8 70 Series is discontinued, and Euro VI now required under ADR 80/04, this is the final nail in the coffin for the 4.5-litre turbo-diesel V8.

WHAT THIS MEANS FOR 70 SERIES BUYERS IN 2026

If you’re buying a new 70 right now: You cannot do a federal pre-rego GVM upgrade.

Your options are:

• Register the vehicle in your state and do a state-based post-rego GVM upgrade

• Or wait until Toyota releases Euro VI compliant models and approvals start coming going through

Fresh suspension, engineered components, and increased payload.

For most private buyers, post-rego works perfectly fine. Manufacturers like Tough Dog Suspension and Lovells Automotive Systems offer a strong range of engineered post-registration GVM upgrade solutions that remain fully available in 2026.

For fleet, finance or resale scenarios where federal pre-rego was preferred, this has changed the landscape.
