Dependable, safe, and enduring 6×6 GVM/GCM upgrades to existing 4×4 vehicles.

6×6 AUSTRALIA’s World-class and World-renowned, User-friendly and Dependable “Workhorse” 6×6 conversions offer the most Safe, Dependable, and Capable GVM/GCM upgrades for standard 4x4s, making what Payload and Tow-rate capacity performance and achievement parameters in what used to be difficult to achieve, now realistically affordable!


In providing stable and strong platforms for Payload carriage and Trailer hauling, at every point (and then some), 6×6 AUSTRALIA’s conversions actually work!

All 6×6 AUSTRALIA’s Payload and Tow-rate capacity (GVM/GCM) upgrade modifications can be designed around drivers on standard car licences if required.

Along with our World-class and Cutting-edge Chassis, Suspension, and Driveline Technology, our Certified/Trades-qualified Craftsmen at 6×6 AUSTRALIA can also provide stylish and bespoke Bodywork with a lasting finish to complete your unique vehicle conversion. Whatever you can imagine, we can finish it with class!


Individual details for each 6×6 build, such as specific Payload/Towing capacity (GVM/GCM) for Certification/Registration, are set according to our client’s individual requirements.

For example, if you want a 6×6 Landcruiser 200

but don’t want a ‘Heavy Vehicle 6×6’ according to Federal Gov’t ADR-compliance GVM/GCM laws (because your spouse for instance isn’t licenced to drive a Heavy Vehicle, or because perhaps you might want to decrease Rego/On-road costs and don’t actually need it to be such a heavyweight), we get it certified according to YOUR requirements.

6×6 AUSTRALIA Pty Ltd have been converting 6x6s for over 30 years, and we have developed a humble confidence in navigating the best course of action there for our customers, to get the best outcome for all. This will come at no extra cost to the customer and is just one more solid reason why you’re far better off spending your hard-earned money with us here at 6×6 AUSTRALIA.

– General Agreement terms for ordinary ‘3-stage build’ contracts (example only) –

NOTE: ‘Extra works’, e.g. fabricating/fitting Long Range Fuel Tanks, fitting Front Suspension lifts, Air-lockers and compressors/accessories, and any custom Bodywork, etc. are calculated separately. Full payment for these are normally required at the build commencement or when contracts are signed;




Initial 10% Deposit of your 6×6 conversion’s overall price will book the build commencement date/time-slot once all the finer details are worked on together with you either by phone, in person (preferred), or by email.

Only after our customer is satisfied, after we know what specific work and components the vehicle requires to how to specifically achieve this (i.e. Diff Ratios and enhanced optional extras such as Remote-Reservoir Shock-absorbers), and once we are all ready to commit, we then draft and sign the build contracts with you (one copy to you “the customer”, one to us “the builder”, one to our accountant, and one to our Contract Law consultant)



‘Stage 2)- Payment’ (50% total conversion price) is normally required at this point in time before Chassis extension work can begin. The final contracts will outline defined Payment Stages for everybody.

6×6 AUSTRALIA now begin sourcing supply of any overseas components. Our Tradesmen begin to strip your original vehicle’s rear Suspension, Extend & Reinforce the Chassis, and manufacture any Suspension and Driveline components in lead-up to their assembly and final fitment.




All conversion works are now complete and ‘Stage 3)- Final Payment’ is required. Our customer’s new 6×6 vehicle is prepared for delivery.

Prior to ‘Stage 3)- Final Payment’ and final handover, all certification required for legal registration is organized by 6×6 AUSTRALIA so that final handover runs smoothly, and our excited customer can begin to use their vehicle right away.

    All 6×6 AUSTRALIA conversion technology is entirely our own, and developed in Australia over the course of 3 decades (since 1984). We lead the world in every measure, from Affordability, Safety, Low-maintenance reliability, User-friendliness, and highly capable performance. There is no competition!


      At 6×6 AUSTRALIA, we are also one of the only 6×6 conversion operators working from a nationally accredited manufacturing facility, registered with The Australian Federal Department of Infrastructure & Regional Development (since 1999). Not all 6x6s are built with this level of assurance. Some have their Modification Certificates signed-off by unethical engineers who don’t care much for Safety.

We urge you to ask our competition if their conversions provide ‘Loadshare’, and see if what they tell you stacks up to honest logic when it comes to Safety. Then compare that to financial outlay on your part.

Please ask us about ‘Loadsharing Twin-axle (Bogie-drive) Suspension’. It’s what we do! So you can tell the difference between a ‘True-Blue 6×6 AUSTRALIAN’ 6×6, and all the rest that are getting around now with 6 wheels under their Chassis. We can explain it all in simple, easy to understand terms and you won’t be deceived by the “Ikea Flatpack-type” jobs designs out there.





Our Loadsharing Coil-spring Suspension and our Power-divider technologies are also Internationally Registered Designs.

Mazda BT-50 6×6

Medium-Lightweight 6x6s (Mazda BT-50; Ford Ranger; Toyota Hilux; Nissan Navara; and Mitsubishi Triton), like all our other 6x6s, are built for increased weight carriage focused on usability, safety, comfort, and reliable performance.

Once converted, in Australia these Mid-sized 6x6s can still be legally operated with a standard car licence (<4,500kg GVM), and safely carry a 2,000kg Payload (4,495kg GVM and 7,995kg GCM).

GVM is the entire weight of the empty/unloaded vehicle itself PLUS anything it’s carrying (Payload), i.e. ‘Gross Vehicle Mass’.

GCM is the entire combined weight of everything including GVM PLUS the weight of your Trailer setup, i.e. ‘Gross Combination Mass’ .

Nissan GU Patrol 6X6

Our ADR heavyweight 6×6 is based on large-size 4x4s, e.g. Nissan Patrol or Toyota Landcruiser range.

For example, our Toyota 79 series Double-Cab Landcruiser 6×6 Workmate model measures Tare 2,650kg (original 4×4 Tare 2,090kg); Payload 3,550kg (original 4×4 Payload 1,110kg); 6,200kg GVM (original 4×4 GVM 3,300kg); and 8,500kg GCM (original 4×4 GCM 6,800kg).

The Y61 Nissan Patrol GU 6×6 ST model is 5,130kg GVM and  8,500kgGCM.

We also do these two particular models in a lightweight configuration with 4,495kg GVM and 7,995kg GCM.

Our 200 series Landcruiser 6×6 GXL model has a 3,080kgPayload (original 4×4 Payload 705kg); 6,080kgGVM (original 4×4 GVM 3,350kg); and 8,500kgGCM (original 4×4 GCM 6,850kg) in comfort and safety.

Capacity for heavy loads, across all-terrains, and in reliable safety and comfort is and was always our aim.

 WHAT YOU GET FOR YOUR MONEY WITH A CAB-CHASSIS 6X6 CONVERSION: Prices vary between specific conversions depending on original vehicle chassis choice used in conversion, your choice of unique custom optional extras, and in which Federal ADR class of weight capacity (GVM/GCM) you wish your vehicle to reside.

  For instance, you might want your 6×6 able to be legally operated on a standard car licence, and still able to perform as expected. For this, we build you our Medium-Lightweight 6×6 inline with applicable Federal ADR identity plate labeling for the standard car licenced GVM/GCM operator.

  At standard price, vehicles get the usual fully reinforced chassis extension of 1,300mm (minimum) crafted with new folded plate steel chassis-rail sections, fully-welded. Then we use stitched 6mm steel Fisch-plating, and then (for Heavyweight GVM conversions) extensive 4 x 50mm square RHS bracing running beneath the chassis rails.

Your custom order might require a longer chassis too, e.g. for a permanent RV/Camper or Safari bus body. To an extent, this can be as long as you want (max. 1800mm).

Our Heavyweight GVM/GCM 6×6 models include the likes of ‘Wagon to Dual-cab’ 200 series Toyota Landcruiser Sahara/GXL and Y61 Nissan GU Patrol models.


DRIVE-LINE TECHNOLOGY: The Power-divider within the Drive-through diff governs our system’s drive-power distributed to each rear wheel, directing when to release ‘Axle windup’ and when to lock full ‘Drive-power’ down through to the wheels as needed.

The Power-divider controls the full-time 6×6 system and is a legally essential component. The amount of real traction created with four wheels under power, so close to each other is phenomenal. If this power-divider wasn’t so sophisticated, the axles would begin to fight each other and at least one axle would snap. Our Bogie-drives provide phenomenal traction.

TWIN-AXLE SUSPENSION: Our coil-spring Bogie-drive suspensions provide for a smooth and comfortable ride, and superior handling under load. (Registered Design IPRNs No.201712910; No.201714911; & No.201714912)

100% Load-sharing coil-spring suspension system with integrated ‘Roll-steering’ under load.

The integrated ‘Roll-steer’ function provides enhanced stability, especially at speeds >60km/hr, AND ESPECIALLY WHEN FULLY LOADED!

  Working together with it’s Roller-drive power-divider, this setup provides serious traction with all 4 rear wheels under drive-power.

Our builtin ‘Roll-steer’ design also helps decrease tyre-scrubbing. Due to the poor design or complete absence of a power-divider in some other 6×6 systems, ‘Tyre-scrubbing’ is seen as a common costly flaw. This adds to the hidden costs in those already expensive systems.

  6×6 AUSTRALIA usually outsource supply of specially formed & hardened diff gear-sets with Heavy Duty axles, and then machine-form our own ‘Roller-drive’ Power-divider, to complete it’s integration within our Drive-through diff.

All brake parts, and diff-housings, etc. are genuine factory parts according to your vehicle make. These drive-lines, along with our evolutionary Loadsharing/Roll-steering suspension, are a huge part of what makes our system the 6×6 market leader and the envy of our competition.

6×6 AUSTRALIA Toyota Dual-cab 79 series Landcruiser 6×6 cab-chassis conversion

For a heavyweight version of our 6×6, the general formula we use is 10% price increase. This price increase covers necessary build increases such as chassis extension reinforcing materials and workmanship, etc., as well as the exotic full-floating hubs we use in the 2 new rear diffs.

Prices are often negotiable and sometimes we have a discount sale on, e.g. our current EOFY Free Traybody offer .

Also, exactly what optional extra work is involved might effect final pricing, e.g. Bodywork such as a Flatbed tray with or without gates & bars, or a full-blown 13 seat Safari bus body.

Dual-cab Toyota 200 series Landcruiser GXL 6×6

Toyota 200 series Landcruiser 6×6 cab-chassis is usually  completed as a heavyweight GVM, with the following metrics: 6,080kgGVM, 8,500kgGCM, and 3,500kg Tow-capacity. (Unless requested otherwise with your custom order).

If requested otherwise with your custom order, for this vehicle to be driven on a standard car licence, the build will need it’s modification to be individually certified to <4,500kgGVM. This is no extra cost, but part of the overall price. Such details as this just require outlining in your build contract for labeling/certification requirements in legal registration purposes.

For example, some customers require a mid-lightweight GVM/GCM so themselves, their spouse, or employees can still operate it on a car licence (which limits them to operating vehicles no more than 4,495kg GVM).

As these Toyota 200 series Landcruiser 6×6 conversions originally start from a 4×4 wagon body, they require significant bodywork to convert them to a 4×4 Dual-cab ute. This bodywork is needed to be completed prior to beginning the 6×6 chassis and suspension work and is calculated in pricing as an individual extra component of your vehicle conversion.
