Fitting and Care Notes

When fitting the rear suspension arm on your MP9 TKI4, confirm all mounting points are tightened and secure. Inspect for free play after initial runs and carry out routine checks to avoid premature wear.
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 IF423B fit other INFERNO MP9 variants?

The IF423B is designed for the INFERNO MP9 TKI4; other MP9 generations may have different geometry so fit is not guaranteed.

Which fasteners should I reuse when replacing the arm?

If the original pins and screws are in good condition, reuse them. Replace any bent or worn hardware and verify secure mounting before running.

How often should I inspect the rear arms after track sessions?

Check the arms after a few runs or after heavy impacts. Look for cracks, excessive play at mounting points, and any deformation that could affect handling.
