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

Our User-friendly 6×6 Workhorses offer safe, dependable, and highly capable GVM/GCM upgrades for your standard 4×4.

6×6 AUSTRALIA modifications can be designed with consideration for drivers on a standard car licence if required.

Along with our leading-edge chassis, suspension, and driveline offerings, 6×6 AUSTRALIA also provide stylish and bespoke bodywork, with a lasting finish to complete your unique vehicle conversion. Whatever you can imagine, we can build!


Individual details for each 6×6 build, such as specific weight-carrying capacity (GVM/GCM) for certification/registration, can usually be set according to our client’s individual desires. For example, if you want a 6×6 Landcruiser 200, but don’t want it to be registered as a Heavyweight GVM/GCM 6×6 (because your spouse isn’t licenced to drive a heavy vehicle or because you want to reduce costs and don’t actually need it to be such a heavy lifter), we can get it certified according to you requirements. This will come at no extra cost to the customer.


General terms of contract:

(This is a general outline. Each build takes a number of weeks, so customers are usually updated on progress every 2 weeks by phone or email with photos, or sometimes both as it approaches completion)

1)- Initial payment of 10% Deposit of individual 6×6 conversion price books the vehicle’s build commencement date/time-slot.

NOTE: ‘Extra works’, e.g. fabricating/fitting Long Range Fuel Tanks, fitting Front Suspension lifts, Air-lockers and compressors/accessories, Reservoir Shock Absorbers, and any custom bodywork, etc. are calculated separately. Full payment for these are usually required at the build commencement;

2)- Upon receipt of the initial 10% deposit, 6×6 AUSTRALIA books your vehicle’s commencement date/timeslot and begins organizing supply of some overseas components;

3)- On arriving at allocated start-date, 6×6 AUSTRALIA take possession of the vehicle, and begin conversion works. Stage 2 payment of 50% total conversion price is usually required at this time.

4)- Upon reaching date of completion, Stage 3 final payment is required, and client’s new 6×6 vehicle is then handed back over to them.

Prior to Stage 3 payment and final handover, all certification required for legal registration is organized by 6×6 AUSTRALIA so that final handover goes smoothly, and our excited clients can begin to use their vehicle right away.

If you still have questions, please check our “COMMON QUESTIONS” page and if the answer isn’t there, please feel welcome to contact us and ask.

     All 6×6 AUSTRALIA conversions are done to existing 4×4 chassis platforms. The 6×6 Bogie-drive technology is entirely our own, including the Drive-through Diff with Power-divider driveline, and Loadsharing Coil-spring suspension with integrated ‘Roll-steer’. This technology was developed right here in Australia over the course of 3 decades (since 1984) and leads the world in affordability, safety, low-maintenance reliability, user-friendliness, and capability performance.

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.

Our Loadshare coil-spring suspension and our Roller-drive Power-divider technologies are also internationally registered designs.

6×6 AUSTRALIA Federal Identity Plate Approval (IPA) numbers include:

Toyota 75 series Landcruiser 6×6 IPA#13434 for Medium/Lightweight GVM/GCM, and IPA#13436 for Heavyweight GVM/GCM;

-Current model Toyota 79 series Landcruiser (current model) 6×6 IPA#43189 for Medium/Lightweight GVM/GCM, and IPA#46527 for Heavyweight GVM/GCM;

-Current model Toyota 200 series Landcruiser 6×6 (current model) IPA#48397 for Heavyweight GVM/GCM;

Nissan GU (Y61) Patrol 6×6 IPA#47606 for Medium/Lightweight GVM/GCM, and  IPA#47607 for Heavyweight GVM/GCM;

-Current model Mazda BT-50 (current model) 6×6 IPA#47852 for Medium/Lightweight GVM/GCM; and

-Current model Ford Ranger 6×6 (current model) IPA#48853 for Medium/Lightweight GVM/GCM.

 We ‘re currently preparing more, including Iveco Daily 5500 6×6 for Heavyweight 8,750kgGVM, and Ford F150 6×6 for Medium-Lightweight GVM/GCM and F350 6×6 for Heavyweight GVM/GCM.

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 Tare 2,090kg); Payload 3,550kg (original Payload 1,110kg); 6,200kg GVM (original GVM 3,300kg); 8,500kg GCM (original GCM 6,800kg). The Y61 Nissan Patrol GU 6×6 ST model is practically the same.

Our 200 series Landcruiser 6×6 GXL model has a 3,080kgPayload (original Payload 705kg); 6,080kgGVM (original GVM 3,350kg); and 8,500kgGCM (original 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 a general idea on prices, we show examples below of our medium-lightweight 6×6 conversion, and our heavyweight 6×6 conversion models.

  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.

For Medium-Lightweight GVM/GCM 6×6 cab-chassis conversions, our standard price is approximately AU$43,000 (Incl. GST).

NOTE: Some of the Medium-Light GVM/GCM vehicles with Automatic transmissions, e.g. Ford Ranger and Mazda BT-50 will cost an extra AU$4,500 (Incl. GST) because of exotic diff ratios used by the original manufacturers of these Automatic Transmission models, which we have to conform with when doing our 6×6 conversion.

  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 extensive 4 x 50mm square RHS bracing running beneath the chassis rails from behind the furthest rear axle to the front of the vehicle beneath the driver’s seat position.

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).

Optional extra chassis lengthening is charged at $2/mm above the standard conversion’s 1,300mm extension, and still finished inline with usual extension/reinforcing materials and methods.

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 (while strangely still remaining such a simple design), the axles would begin to fight each other and eventually before too long at all, at least one axle would snap. Our Bogie-drives provide a phenomenal amount of traction to the rear of your vehicle.

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 each new rear diff. For a standard Heavyweight GVM/GCM cab-chassis 6×6 conversion to a large-size 4×4 vehicle, our price is AU$46,750 (Incl. GST).

Prices are often negotiable and sometimes we have a sale on, for example “End Of Financial Year Sales” for May-June with GST-free pricing.

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 6×6 cab-chassis

There’s a stack of different bodywork options and we can provide them all. Get in touch and let us know what you’d like to see happen.


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 towing 3,500kgTow-capacity. (Unless requested otherwise with your custom order).

These Toyota 200 series cab-chassis 6×6 builds are priced at AU$49,500 (Incl. GST) and are essentially the same as our usual Heavyweight GVM builds, with one special difference that sets it apart. We make both rear axles, on both Heavyweight and Lightweight 200 series 6x6s, with full-floating hubs, and all while still keeping the 200’s complex ABS functional.

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.

For a competitive price, 6×6 AUSTRALIA can provide this bodywork too. General price for our new Landcruiser Dual-cab bodywork is AU$21,900 (Incl. GST). Metallic or Pearl paint is extra $1,320 (Incl. GST).


 General description of small selection of some of our Custom Automotive Bodyworks, with general pricing to give a basic idea:

GENERAL PRICE OF CUSTOM LARGE-SIZED 6×6 WITH RV/CAMPER (incl. fit-out to custom order specs): General pricing for a brand new Large-sized (Nissan Patrol/Toyota Landcruiser) permanent Pop-top RV/Camper 6×6, seats/berths 2 Adults, ranges between AU$300,000-$750,000 (Incl. GST) including new base vehicle chassis (e.g. Landcruiser, or Patrol, or F350, or other large-sized 4×4). For example, general market price for new Toyota 79 series Landcruiser is currently AU$65,000. Add the price of the 6×6 conversion ($45,000) plus bodywork of AU$205,000 and we have AU$315,000 combined.

Price for the same type of permanently fixed RV/Camper on a mid-size 6X6, e.g. Mazda BT-50, is approximately 5% less. Final price depends on consideration of your entire package. Broad options can be discussed upon inquiry. Resale value on these is approx. 50% better than the base vehicle chassis used in conversion as they hold their value really well.
