DUAL CAB CONVERSIONS, CHASSIS EXTENSIONS AND BRACING

We offer a range of more involved vehicle modifications at TJM 4×4 Megastores. We truly believe in being a one stop shop in Brisbane and the Gold Coast for all your vehicle modification needs.

As such we expanded our services to include the conversion of the popular Toyota 200 Series Landcruiser Wagons into Dual Cabs and Utility chassis extensions through our friends at ASG 4×4 in Toowoomba, QLD. We also offer the supply and install of chassis bracing kits for dual cab utility vehicles in house.

Dual Cab Conversions - ASG 4x4

Teaming up with Australia’s leading dual cab conversion specialists ASG 4×4, we can now offer a local Brisbane and Gold Coast based solution for your conversion needs. We have an ASG 4×4 Converted Dual Cab on fleet and can walk you through the entire conversion process without the need to visit Toowoomba.

Through our TJM Stores and Spinifex Manufacturing Arm we can take care of the full fit out including the rear body after the conversion process

Chassis Extensions

Often the load carrying ability and ride of a dual cab can be improved by extending the wheelbase. By pushing the rear axle back it allows for better weight distribution and improved ride and towing characteristics. Again, this service is completed by ASG 4×4 and is covered by all relevant engineering support that has been tried and tested.

Chassis Bracing

Late model 4wd’s are also particularly prone to ‘bent rear chassis’, partly due to the chassis size and thickness and the remarkably high advertised ‘rated’ towing and load capacities. Towing and carrying loads that are not ideally distributed can accelerate cracking and failure, which is made even worse when done over rough or rugged terrain.


Overloaded vehicles are dangerous and unroadworthy, heavy duty suspensions and load assist airbags will not solve the problem of overloading. 


The Superior Engineering range of Weld-on chassis braces, dramatically increases the sectional strength of the chassis in key critical areas.

Coil Conversions

We are Authorised agents for Superior Engineering and can offer their full range of road legal coil conversion kits.

Convert your leaf sprung Toyota 79 Series Landcruiser, Toyota Hilux, Mazda BT50 or Ford Ranger to a more compliant ride and better handling both on and off road with one of our Superior Engineering Coil Conversion Kits, designed, tested and manufactured right here in Brisbane, QLD to suit all Australian conditions.
