Refine Handling with the Kyosho IFW634-46S 46T Spur

The Kyosho IFW634-46S is a lightweight 46-tooth spur gear crafted to enhance throttle feel when combined with a smaller differential. This setup promotes faster acceleration response and gentler deceleration, and the IF403B diff case set is required to install the part correctly.

Enhanced Drive Characteristics

Fitting the IFW634-46S alongside a reduced-size diff sharpens acceleration transitions and provides a smoother slowing profile. That balance helps drivers maintain consistent corner exits and lap consistency.

Which Models and How to Fit

This spur gear is made for MP10 and MP9 platforms and replaces the original differential housing with a more compact unit. To ensure accurate gear mesh and secure fitting you must use the IF403B diff case set.
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 IFW634-46S compatible with both MP10 and MP9?

Yes, it is designed for MP10 and MP9 chassis but requires the IF403B diff case set to swap the stock housing for the smaller unit.

Will I need to change pinion gears after fitting this spur?

You may need to re-check pinion to spur mesh and adjust pinion spacing if necessary, but there is no mandated pinion swap tied to the IFW634-46S itself.

Does the IF403B come with the spur?

The IF403B diff case set is required for installation but is sold separately; confirm you have the diff case set before fitting the IFW634-46S.
