GVM Upgrade Frequently Asked Questions
Why does the JMACX bolt in coil conversion use the 5 link suspension system?
The biggest advantage to the 5 link suspension set-up is its load carrying stability from the REAR PANHARD (the 5th link). This 5th link allows the rear differential to stay fixed and stabilised when cornering or with any side load on the vehicle, without this rear panhard the differential would be able to move freely side to side from the chassis this would be suitable for light vehicles with low centre of gravity, rock crawling 4wd or a drag car that needs to only go in a straight line. However when it comes to a heavy load carrying vehicle this would not be safe as it would not be able to support the side load on the suspension set-up hence where the 5 link came out on top. The 70 series is a load carrying vehicle with a high centre of gravity so the rear panhard is a must to keep the suspension centred and assist in the stability and safety of the vehicle.
Should I have the highest rear axle load rating on the market?
While some other businesses may rerate axles at a higher capacity this can lead to excessive weight loading on the rear of the vehicle. With excessive leverage there is stress on the chassis springs and lack of control over the front of the vehicle diminishing the safety and stability of your vehicle. The weight proportioning and distribution of your vehicle should be balanced between the front and rear axle. In some cases bigger isn’t better. This JMACX 2850Kg rear axle load rating is more than adequate to ensure the balance of safety and stability for your vehicle.
How strong are the upgraded differential and axles?
The JMACX differential housings are full fabricated units that exceed the strength of the factory original unit. JMACX axles are the strongest production manufactured axle for Landcruiser available. 100% Australian made and designed.
Do I Require Flares?
Flares are required on all vehicles that the tyre protrude outside of the guard or mudflap check with your installer for the fitment of your selected wheel and tyre combination its the obligation of the fitting facility to ensure that the wheel and tyre combination selected for your specific vehicle is covered by the flare and mudflap any costs associated with this task would be passed to the customer.
Does the wide track diff for the coil conversion correct the rear vehicle track?
Yes. Factory vehicles have a width difference from the front to the rear axle of 100mm. The JMACX coil conversion comes with a wide track diff as a track correction of the vehicle and increases the stability of the vehicle. Note: wheel spacers and large offset wheels over 25mm are illegal in all states of Australia.
Can I have a custom colour?
We offer custom colour for Coil Conversion cradles and radius arms. Coil conversion cradles come standard as satin black finish, for no extra charge choose from our colour range. Radius arms are gold SA-5 coated as standard. For an additional charge of $80 you can select a colour from our colour range. If you would like other parts custom coloured eg. coils, differential etc please contact your local JMACX authorised facility to have your parts custom coloured for an additional charge.
Do the upgrades contain parts that are custom and maybe difficult to find?
Our diffs maintain all factory brakes, hubs, bearings, seals, diff lockers etc. Most parts maintain OEM Toyota bushes, so parts can be easily accessible anywhere in the world.
Will the GVM upgrade affect my insurance?
No, but it is up to each individual to check with their insurer. Generally insurers only require the vehicle to be legal.
How long will JMACX take to fit the coil conversion to my vehicle?
The Conversion will take around 7-14 working days depending on what accessories are being fitted to the vehicle.
