Kyosho IF403B Case Set for INFERNO MP9 Models

The Kyosho IF403B Differential Case Set is a practical spare designed for INFERNO MP9 cars like MP9, MP9e and GT3. It helps sustain smooth drivetrain operation so your car responds predictably on a range of surfaces.

Where It Fits and What It Does

Made to fit both front and rear differentials of the MP9 range, this case set is a direct replacement that preserves gear alignment and overall drivetrain function. Use it as part of routine service to avoid handling inconsistencies.
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.

Is the IF403B a direct swap for stock cases?

Yes, the IF403B replaces the original MP9 front and rear diff cases without modification when used with compatible internals.

Will upgrading the case change handling?

Replacing a worn or damaged case restores correct gear alignment, which in turn improves consistency in handling rather than changing the baseline setup.

How do I check for internal wear?

Disassemble the diff and inspect gears, bearings and seals for scoring or play. Replace components that show visible wear to prevent further drivetrain issues.
