Precise Control for Setup Changes

Using a 64 pitch design like this lets you make subtle adjustments to speed and acceleration. That finer resolution is useful when you need small changes to balance handling and top speed.

Suitable for Racing and Hobby Driving

Do I need a special pinion to use this spur?

You should pair the 3RACING 3RAC-SG6477 with a 64 pitch pinion that matches your motor shaft size and pinion bore. Confirm fit before running the car.

Will changing to 77T lower top speed?

Increasing tooth count typically reduces top speed slightly while improving acceleration and drivability; exact change depends on your pinion and motor combination.

How often should I inspect the spur gear?

Check the gear for wear and proper mesh after a few runs and then regularly as part of routine maintenance, especially after impacts or heavy use.
