Our Bogie-drive 6×6 conversions are designed simply to navigate challenging off-road locations, and carry and tow heavier payload and trailer masses with user-friendly ease, low-maintenance / economical capability, and in ultimate safety and comfort.
To this end, our symmetrical Loadsharing, Coil Spring (optional Airbags), and Disc Brake Bogie-drive systems with integrated Roll-steer function (“the Bogie”) was born out of necessity in the early-1980s when our initial incarnations as a Mechanical & Smash Repairs business needed a medium-sized tow truck for tackling its regional NRMA operations at the time.

Our excellent suspension and driveline systems for bogie-drive 6×6 vehicles are designed and manufactured by our trade-certified teams for quality workmanship.
Check the following photos for glimpses of what’s offered at our federally registered Design and Production facility (No.D115 and No.P11581) in Coraki (Northern Rivers, NSW).
Our simple and effective design,evolving from the mid-1990s to date is modeled indirectly off railway train passenger/freight carriage bogies with our founder’s time (Bob James, founder and General Manager/CEO) as Electrical Fitter Foreman in Sydney Yard (NSW Rail – @1973-1983).
The Bogie’s design was adapted from heavy duty railway train carriages to match contemporary automotive mechanical materials and technologies, and is designed for simple, heavy duty reliability in responsibly carrying heavy payloads above the typical light commercial chassis/suspension/driveline combination’s usual abilities, with relative ease and in ultimate safety for the passengers/crew and freight on-board.

Key aspects found nowhere else among other bogie-drive systems include our protected design’s ‘Symmetrical Loadshare Beam’ suspension; our integrated/functional ‘Roll-steering’ suspension; and our driveline’s integrated ‘Roller-drive Power-divider’ built internal to the drive-through differential assembly (also built with an incorporated ‘ARB Air Locker’ diff lock).
“Loadshare suspension” – ‘Loadsharing suspension’ in Mechanical Engineering is an advanced requirement within our Federal Australian Design Rule legislation (“ADR-43/04, 8. LOAD SHARING SUSPENSION”) on all twin axle suspension/driveline systems (AKA “Bogie-drive / 6×6”) that carry above 4.5tonnes Gross Vehicle Mass (GVM), and which GVM is the car licence holder’s legal limits, upwards whereof at the official ‘Heavy Vehicle’ registration and insurance becomes mandatory. No other bogie-drive suspension designs can honestly claim this key engineering concept within their suspension systems. It’s only part of what makes ours the best 6×6 conversion available.
The ‘Roller-drive Power-divider Mechanism’ divides the Drivepower between the rear four wheels. With the bulk traction from these four wheels under full-time/on-demand Drivepower from the Engine and Transmission, located so close to one another, there is a significant amount of physical force being forced through the internal gear components between the Engine/Transmission to where the rubber meets the road.
Without this ingenious little control mechanism built into our unique Drive-through differential assembly, this extraordinary amount of traction would soon damage the gears, axles, and bearings. Our integrated Power-divider mechanism’s current generation (Gen.15, early-2023 – proprietary 6×6 Australia Pty Ltd technology), a handsome piece of ingenuity, requires we keep its details top secret.
For sake of fuel economy, the Power-divider mechanism tension is primed (i.e., pre-tensioned) for Drivepower, so that once cruising at highway speeds, the Power-divider is no longer required to provide Drivepower to the Rearmost axle, and releases the pre-tension to allow the drive to flow economically until demanded for.
So refined is the mechanism’s action (both On- and Off-road), the moment it begins to sense the slightest loss of any traction at Drive-through axle’s wheels, for example, in the slippery wet highway, it mechanically locks Drivepower internally, and full drive is divided between all four rear wheels. For extreme off-road requirements, its in-built ‘ARB Air Locker’ Diff Lock can be activated, which sees an extremely capable vehicle come to life.
“Functional Roll-steer” – Integrated and complementary to the suspension’s protected IP Loadshare Beam designs (Registered Design Nos.201714910; 201714911; and 201714912) is one aspect of our technology no other 6×6 builder can compare to.
This subtle performance technology enables a sensational experience of the phenomenons in natural physical forces (e.g., Centrifugal & Gravitational “G” Forces) as the vehicle carrying extraordinary massive payloads navigate sweeping on-road terrains and challenging off-road extremes.
No photos or video footage does this sensation justice as the revolutionary and protected suspension design uses centrifugal force from physical carriage of its extra-heavy payload mass as it maneouvres corners at speed to manipulate the suspension, slightly similar to how a skateboard steers by shifting weight across it centre axis to navigate corners. In order to be truly appreciated, it has to be fully experienced on a test drive while our technicians simultaneously explain its actions.
The comfort and security of feeling safe and in control of the heavy payload gives the operator great peace of mind and is remarkable to sense during operation.

– Which make/model of our 6×6 conversions you require;
– What you intend to use your new 6×6 vehicle for;
– What extras you’d like to know availability and prices for (e.g., Bodyworks, like Dual-cabs from Wagons / Flatbeds / 3-berth RVs / 12-seat Safari buses / Gullwing Canopies with drawers / Cabinets, and/or Fuel / Water Tanks);
– What State/Territory your vehicle is to be registered in; and
– A brand new / unregistered vehicle, or a previously registered / used vehicle to be converted? The modification certificate from our Mechanical Engineer signatories are different for each type of 6×6 modification as per government (Federal or between each State/Territory).
Please feel welcome to inquire on any other related questions you have about your new 6×6 conversion.
