Fine-Tuned Pinion for Reliable Drivetrains

The Yokomo PG-4821A pinion gear is manufactured from hard-coated aluminum to provide a lightweight, dependable option for your RC car's drivetrain. Its 21-tooth count and 48 pitch specification ensure correct engagement with matching spur gears for consistent power transfer.

Built to Last Under Load

The hard coating on this pinion reduces surface wear and helps the gear hold up during frequent runs. Aluminum construction keeps rotating mass low, which can improve throttle response without adding unnecessary weight.

Fitment and 1/10 Scale Use

This 21T, 48 pitch pinion is suited to a wide range of 1/10 scale RC vehicles that use the same gear pitch. Pair the Yokomo PG-4821A with compatible spur gears and check gear mesh for quiet, efficient operation whether you are racing or bashing.
Remark :
Due to limited stock availability, please notice that some Yokomo 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.

Which RC models work with this pinion?

Any 1/10 scale car or truck that uses a 48 pitch gearset and accepts a 21-tooth pinion can fit the Yokomo PG-4821A with the correct shaft fitment.

Why choose a hard-coated aluminum pinion?

The hard coating helps resist wear from the spur gear, while aluminum keeps weight down compared with steel, helping preserve motor and drivetrain efficiency.

How should I set gear mesh with this pinion?

Use a thin piece of paper between the pinion and spur, tighten the motor mount, then remove the paper to achieve a snug but free-running mesh. Recheck after a few runs.

Any maintenance tips for longevity?

Inspect the gear teeth regularly for nicks, confirm the hard coating remains intact, and keep the mesh clean of grit to extend service life.
