MP9 Ring Gear Upgrade Guide

The Kyosho IF406-43 is a well-made 43-tooth ring gear intended for MP9 chassis. It supports consistent meshing and is suitable for both track and hobby use.

Balanced Drive Characteristics

Optimised to work with MP9 drivetrain geometry, the IF406-43 helps reduce vibration and delivers even power distribution across the system. Quality construction helps maintain alignment under stress.

Practical Fitment Advice

Clean the gear area before fitting and verify the mesh through the full suspension travel. Regular inspection and light lubrication will keep the drivetrain running smoothly and quietly.
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.

What checks should I do after fitting the ring gear?

Verify pinion mesh, spin the drivetrain by hand to check for binding, and run a short test at low throttle to listen for abnormal noise.

Is an aftermarket pinion required?

You can use OEM or quality aftermarket pinions; the important factor is correct tooth profile and accurate mesh with the IF406-43.

When should the ring gear be replaced?

Replace when teeth show wear, rounding or chipping, or if you notice persistent skipping. Regular checks help spot these signs early.
