HOBBYWING 15T Pinion for 1/8 Scale Off-Road

The HOBBYWING 15T 5mm M1 steel pinion gear is aimed at enthusiasts running 1/8th buggies and truggies who need dependable gearing options. Made from 40CR steel, it withstands hard running and keeps tooth profiles stable under load.

Adjusting Torque Versus Top Speed

Changing the pinion tooth count is the simplest way to tune drive behaviour. Fewer teeth yield better low end torque for rough terrain, while more teeth increase top speed for straight sections.

Installation Notes and Compatibility

This 15T pinion uses a 5mm bore and a 1.0mm modulus, matching many common 1/8th off-road motor shafts. Its tough steel construction helps it resist wear during frequent track sessions or rough field use.

What shaft size should my motor have to use this pinion?

This pinion is manufactured for a 5mm motor shaft. If your motor shaft is a different size you will need an adapter or a different pinion to match the shaft diameter.

Can I use this gear on on-road cars?

It is primarily intended for 1/8th off-road machines but will fit any model that accepts a 5mm bore and M1 modulus pinion. Check clearance and mesh before running on an on-road chassis.

How should I inspect the pinion after use?

Regularly check teeth for chipping and verify the set screw is tight. Clean debris from the gear and inspect mesh to prevent uneven wear.
