Precision Fit Pinion from Kyosho

The Kyosho PNGS4821 is a 21-tooth, 48-pitch steel pinion engineered to provide reliable meshing in RC vehicles. It serves as a straightforward option for replacing worn pinions while maintaining accurate gear contact.

Reliable Engagement for Everyday Running

Its steel build ensures a strong mating surface with matching spur gears, helping to maintain consistent drive characteristics. Regular inspection of mesh and tooth condition will keep performance predictable.

Compatibility with 1/10 Scale Gearing

The 21T-48P size is commonly used across many 1/10 scale models that specify 48-pitch gear systems. Verify your car's gear pitch and tooth count before fitting to ensure proper compatibility.
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.

How do I tell if my spur gear matches this pinion?

Check that your spur gear is 48-pitch and that the tooth counts align with your desired ratio. The 21-tooth pinion will mesh correctly only with the same pitch spur.

Are there tune-up tips after installing the pinion?

After fitting, run the vehicle at low speed to listen for mesh noise, then recheck tightness of the set screw and motor mount. Minor adjustments often improve life and smoothness.

When should the pinion be replaced?

Replace the pinion if you notice worn or chipped teeth, excessive backlash, or persistent noise that does not improve with mesh adjustment.
