Fresh Performance with the Kyosho IFW634-46S Spur Gear

The Kyosho IFW634-46S is a lightweight 46T spur designed to improve overall drive feel by working with a smaller differential. Fitting this gear delivers snappier acceleration and smoother slowing, and it needs the IF403B diff case set for accurate installation.

How It Affects Speed Delivery

Pairing the IFW634-46S with a reduced-size diff sharpens throttle transitions and gives more predictable deceleration. These changes suit drivers looking for more responsive exits and steadier mid-corner behaviour.

Compatibility Notes and Fit Process

Made to work with MP10 and MP9 series models, this spur replaces the standard differential housing where applicable. The IF403B diff case set is required to ensure correct fit and gear mesh.
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.

Can I install IFW634-46S on an MP9 the same way as an MP10?

Yes, the IFW634-46S is compatible with both MP10 and MP9 models provided you use the IF403B diff case set to adapt the housing size.

Will this spur gear change gearing ratios?

The IFW634-46S is a 46T spur; changing to it alters drive feel through diff sizing rather than altering pinion tooth count. Be sure to set correct mesh after installation.

Is additional hardware needed for a secure fit?

You will need the IF403B diff case set for a proper fit. Also double check diff shims and gear mesh during assembly for reliable long term operation.
