The Kyosho IF403B Differential Case Set is a serviceable component aimed at improving the drivetrain reliability of INFERNO MP9 series cars, including MP9, MP9e and GT3. It supports consistent traction and predictable handling across different track surfaces.

Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will the IF403B fit my MP9e conversion?

Yes. The IF403B is made to match MP9 series specifications and is compatible with MP9e setups that use the standard differential layout.

Any tips for installing the differential case?

Clean mating surfaces, check gear mesh before final assembly, and use the recommended screws to avoid stressing the housing. Test spin the diff by hand to confirm smooth rotation.

How can I tell if the case needs replacing?

Look for play in the differential, unusual noises, or leaking fluid around the diff area. If handling feels inconsistent, swapping the case is a good maintenance step.
