GVM Kit Frequently Asked Questions
How strong is the upgraded differential and axles?
JMACX differential housings are full fabricated units that exceed the strength of the factory original unit. JMACX axles are the strongest production manufactured 300M chromoly axle for Toyota Landcruiser available. 100% Australian made and designed.
How long will JMACX need my vehicle for?
The Toyota Landcruiser 79 Series leaf GVM upgrade will take approximately 7-14 working days depending on what accessories are being fitted to the vehicle.
Does the wide track diff correct the rear vehicle track?
Yes. Factory vehicles have a width difference from the front to the rear axle of 100mm. The JMACX leaf spring GVM upgrade 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 radius arms. Radius arms are gold SA-5 coated as standard. For an additional charge of $80 you can select a colour from our colour range. You will be prompted to select your radius arm colour as you continue building your quote. 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 differentials 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.
