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

Our User-friendly 6×6 Workhorses modifications offer a very capable, Safe, and dependable GVM/GCM upgrade to your existing 4×4. Our 6x6s can be designed for drivers with standard car licence.

We also provide stylish, bespoke bodywork with a lasting finish to complete your vehicle’s unique specifications.

Normally, except for most of the general suspension components, each conversion we build is unique.

General terms of contract:

This is only a general outline of how we usually operate. As these builds take a number of weeks, Customers are generally updated on progress every 3-4 weeks by phone call. We want to be approachable for our customers as we build more than just a highly capable ‘Workhorse’ of sorts with our 6×6 conversions.

Once a Customer and 6×6 AUSTRALIA are agreed in regard to final appearance and capabilities, total price of contract, and a time schedule with dates to work by is drawn up, so Customers and 6×6 AUSTRALIA can each know the final price, when each party’s commitments are due, and exactly what the timeline for scope of work is.

i)- Customer initially pays 10% Deposit of their 6×6 conversion price (‘Extra works’, for example Long Range Fuel Tanks, Front Suspension lifts, Reservoir Shock-absorbers, and Bodywork, etc. are calculated separately), booking for themselves a time-slot for build commencement;

ii)- Upon receipt of this deposit, 6×6 AUSTRALIA begins organizing logistical overseas supply of some components;

iii)- Upon arriving at date of allocated time-slot, 6×6 AUSTRALIA take possession of Customer’s vehicle, and begin it’s conversion. Stage 2 payment of 50% total agreed price (plus full price of any ‘Extra works’) is required at this time. Once Stage 2 payment and vehicle cab-chassis are received by 6×6 AUSTRALIA, the actual chassis work begins;

iii)- Upon reaching date of completion (set out in the build contract), Stage 3 payment is required, and the Customer’s vehicle with completed 6×6 conversion is handed over.

Prior to Stage 3 payment and final handover, all certification required for legal registration is organized so final handover goes smoothly and Customer can begin to use their vehicle.

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 (preferably by email).

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

At 6×6 AUSTRALIA, we are one of the only businesses that operate 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;

-79 series Landcruiser 6×6 IPA#43189 for Medium/Lightweight GVM/GCM, and IPA#46527 for Heavyweight GVM/GCM;

-200 series Landcruiser 6×6 IPA#48397 for Heavyweight GVM/GCM;

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

-Mazda BT-50 6×6 IPA#47852 for Medium/Lightweight GVM/GCM; and

-Ford Ranger 6×6 IPA#48853 for Medium/Lightweight GVM/GCM is pending, due November 2017.

 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-sized 6x6s (Mazda BT-50; Ford Ranger; Toyota Hilux; Nissan Navara; etc.), like all our other 6x6s, are built for increased weight carriage focused on safety, comfort, and reliability.

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).


Nissan GU Patrol 6X6

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

Our Toyota 79 series Landcruiser 6×6 Workmate model (for example) measures Tare 2,650kg; Payload 3,550kg; 6,200kg GVM; 8,500kg GCM. Nissan GU Patrol 6×6 ST model is practically the same.

Our 200 series Landcruiser 6×6 GXL model has a 3,080kgPayload; 6,080kgGVM; and 8,500kgGCM in comfort and safety.

Capacity for heavy loads across all-terrains is always our aim.

 WHAT YOU GET FOR YOUR MONEY WITH A BASIC CAB-CHASSIS CONVERSION: Prices vary between specific conversions depending on your choice of custom options, and in which Federal ADR class of weight capacity you wish your vehicle.

  You might want a truck operating on a standard car licence. For this, we decrease the load-bearing limit of your suspension build, lightening it’s GVM/GCM inline with Federal ID plate labeling for the standard car licenced operators.

GVM is the weight of the vehicle itself (Tare weight), PLUS anything it’s carrying (Payload), i.e. ‘Gross Vehicle Mass’. GCM is everything including the GVM, PLUS the weight of your Trailer setup, i.e. ‘Gross Combination Mass’ .

For a basic Medium-Light GVM/GCM 6×6 cab-chassis conversion, our price is AUD$42,500 (incl. GST). NOTE: Medium-Light GVM Automatic transmission Mazda BT-50 & Ford Ranger conversions are extra AUD$4,500.

Dual-cab Mazda BT-50 6×6 with flatbed traybody (awaiting slide-on Pop-top RV/Camper body to be fitted)

For this price, to start with, you’ll get the usual fully reinforced chassis extension of 1,000mm minimum, crafted with fully welded, high quality, new folded plate steel chassis-rail sections.

Your custom order might require a longer chassis too, e.g. for a permanent RV/Camper body. To an extent, this can be as long as you want it.

We can do this all, depending on what your desires (and your budget) dictate. For optional extra chassis lengthening with mandatory reinforcing, we charge $2,000/m after the normal 1,000mm in the basic conversion. This includes folded 3-5mm steel plate rail sections, with mandatory 6mm Fish-plate sections along the external face.

Details are negotiated and options included in final contract, prior to build.

We’ll normally utilize your existing rear axle, discarding it’s suspension and moving this diff to the rearmost position in the bogie setup, building an entirely new Drive-through diff for the front axle of the Bogie. NOTE: Exceptions include Mazda BT-50 & Ford Ranger with Auto transmissions, and some 200 series Landcruisers. These exceptions require extra diff components compared to our usual basic conversions.

After this, you’ll get our 50/50 Loadshare coil-spring suspension system fully welded to your new reinforced heavy-duty chassis section. Then we obtain genuine factory parts according to your vehicle make, i.e. Toyota parts for Toyota conversions, Mazda, for Mazda, or Nissan for Nissan.

DRIVE-LINE TECHNOLOGY: The Power-divider governs our system’s drive-power from inside the Drive-through  differential, directing when to release ‘Axle windup’ and when to lock full ‘Drive-power’ down through the axles to the wheels.

The Power-divider controls the drive-force required to make it a true full-time 6×6 system, allocating it when required, and releasing the ‘Windup’ when required, thus dividing the power and avoiding broken axles, while at same time ‘driving’ the axles. The amount of traction created with four wheels under power, in close proximity to each other is phenomenal. If this power-divider wasn’t so sophisticated (while remaining so simple), the axles begin to fight each other and eventually before too long at all, the axles 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 suspension provide a smooth, 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 at speeds above 60km/hr,  ESPECIALLY WHEN IT’S FULLY LOADED!

  It’s Roller-drive power-divider gives it serious traction with all 4 rear wheels under drive-power. Our builtin ‘Roll-steer’ design helps decrease tyre-scrubbing too, seen as a common costly flaw in other 6×6 systems, adding a hidden cost to other systems which is often missed by their customers.

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

All brake parts, and diff-housings, etc. are genuine factory parts according to your vehicle make. These drive-lines are the piece other 6×6 builders long for, and part of what makes our systems the market leader and envy of our competition.

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

For a heavyweight version of our 6×6, the general rule we use is 10% increase in price. For a standard Heavyweight GVM/GCM cab-chassis 6×6 conversion to a large-size 4×4 vehicle, our price is AUD$46,750 (incl. GST).

Prices are often negotiable and sometimes we have a sale on, e.g “EOFY Sales” for the month of August with GST free. Also, exactly what optional extra work is involved will effect pricing, e.g. Bodywork such as a Flatbed tray with or without gates & bars, or a full-blown 13 seat Safari bus body.

There’s a stack of different bodywork options and we can provide them all. Alternatively, you might have a local provider near to where you live who can do your job more logistically convenient to you? In this case, we can adjust your order and organize it’s workflow accordingly as we’re happy to network with your local bodywork shop too. 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 AUD$50,000 (incl. GST) and are essentially the same as our usual Heavyweight GVM builds (priced at $46,750, Incl. GST), only with one special difference setting this 6×6 apart from anything else around. We make both axles, on Heavyweight and Lightweight 200 series 6x6s both, using free-floating hubs, and integrating these with Landcruiser parts, all while still managing to keep the 200’s complex ABS system 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. It just needs to be outlined when writing your contract, so the right label and certification is applied to your rig for 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).

 These details are worked out prior to you placing your custom order.

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 Dual-cab ute.

For a reasonable and competitive price, 6×6 AUSTRALIA can provide this bodywork too. General price for our new Landcruiser Dual-cab bodywork is $22,200 (Incl. GST). Metallic or Pearl paint is $1,320 (incl. GST) extra.
