Accurate Pinion for Better Driveability

The Yokomo PG-4821A comes with a hard-coated aluminum construction that keeps weight down while providing a robust mating surface. With 21 teeth and a 48 pitch, it meshes with standard spur gears to deliver steady torque transfer.

Designed for Longevity

The surface coating resists wear from the spur gear and helps maintain tooth profile over time. The light aluminum body reduces rotational drag and supports snappier throttle response on both street and off-road layouts.

Installation Notes and Fitment

Suitable for a variety of 1/10 scale vehicles using 48 pitch gear systems, the Yokomo PG-4821A should be installed with correct gear mesh settings and secure fastening to prevent slippage during use.
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.

What tools are needed to fit this pinion?

A motor mount tool or Allen key for the set screw and a small feeler or paper to set mesh are usually all you need to fit the Yokomo PG-4821A correctly.

Can this pinion handle high power setups?

The hard coating helps resist wear, but check your motor and driving style; heavier power may increase wear on both pinion and spur, so monitor gear condition closely.

Should I balance this with my spur gear?

Proper mesh and alignment are more important than balancing weight; ensure the pinion and spur sit concentric to the motor and gearbox for smooth operation.

Is a 21T common for 1/10 models?

Yes, 21T is a common tooth count for tuning acceleration and top speed in 1/10 scale cars when used with 48 pitch spurs; changing teeth alters the drive ratio.
