Upgrade Gear Mesh with Kyosho PNGS4821

The Kyosho PNGS4821 is a 21-tooth, 48-pitch steel pinion gear made to give dependable meshing and longevity for RC vehicles. This compact steel gear is a solid option for hobbyists who want steady drivetrain engagement without fuss.

Built for Smooth Power Transfer

Forged from quality steel, the pinion meshes accurately with matching spur gears to reduce backlash and help maintain consistent power delivery. Its precise tooth profile helps avoid slippage under load whether you are tweaking the setup for track days or weekend runs.

Fits Common 1/10 Scale Drivetrains

The 21T-48P sizing makes this pinion compatible with many 1/10 scale setups. Fitting is straightforward, and with basic alignment and mesh checks you can have it installed quickly. Always verify your specific model specifications before fitting.
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.

Will the Kyosho PNGS4821 fit my motor shaft and spur gear?

It fits systems that use a 48-pitch, 21-tooth pinion. Check your motor shaft style and spur gear pitch to confirm compatibility before purchase.

What tools do I need to install this pinion?

Basic tools like a hex driver for the set screw and a small spanner for motor mounts are usually enough. Adjust mesh carefully to avoid tooth damage.

How should I maintain the pinion for long life?

Keep gears free of grit, inspect teeth for wear, and use a light, appropriate lubricant on the spur-pinion interface to extend service life.
