Precision Steel Pinion for RC Drivetrains

The Kyosho PNGS4821 is a 21-tooth, 48-pitch steel pinion designed to deliver consistent engagement across your drivetrain. Its robust construction helps hobbyists maintain predictable gear action during setup and running.

Smooth Torque Delivery

Made from hardened steel, this pinion provides accurate tooth contact with compatible spur gears to help smooth torque transfer. Proper mesh adjustment will maximise life and reduce noise during operation.

Easy Fitment on 1/10 Scale Models

The 21T-48P format is common among 1/10 scale cars, making installation straightforward for most builds. Check gear pitch and motor shaft match before installation to ensure a clean fit.
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 check if the PNGS4821 suits my car?

Confirm your spur gear uses 48-pitch and count the teeth needed; measure motor shaft diameter or spline type to ensure a match.

Is mesh adjustment difficult for beginners?

Mesh setup is simple with patience: loosen motor mounts, set mesh by hand, then tighten and recheck. Start with a small gap and fine tune for minimal backlash.

What lubricants are recommended for the gear pair?

Use a light gear grease or specialist RC gear oil sparingly on the spur interface to reduce wear and noise without attracting debris.
