Performance Upgrade Using Kyosho IFW634-46S Spur Gear

The Kyosho IFW634-46S is a lightweight 46T spur gear developed to refine drive characteristics when used with a smaller differential. This combination improves acceleration response and creates a smoother slowing behaviour, and fitting requires the IF403B diff case set to ensure correct alignment.

Better Throttle Response

Installing the IFW634-46S and reducing differential size sharpens acceleration delivery and moderates deceleration for cleaner lap transitions. This setup suits club racers and hobbyists aiming for tighter control on technical tracks.

Installation and Model Compatibility

Designed for the MP10 and MP9 series, this spur gear replaces the standard diff housing with a compact unit. Use the IF403B diff case set to achieve the correct spacing and secure 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.

Does the IFW634-46S require the IF403B to work?

Yes, the IF403B diff case set is required to adapt the smaller differential housing so the IFW634-46S will mount correctly on MP10 and MP9 models.

Will this gear affect handling off road?

On loose or rough surfaces the change in diff size and spur weight can alter traction and braking behaviour, so some suspension and diff tuning may be needed for best results.

How often should I inspect the spur gear?

Inspect the spur for tooth wear, ensure correct mesh with the pinion after each session, and keep the gear area free of grit to prolong component life.
