Balanced spur gear design by 3Racing

The 3Racing 48 Pitch Spur Gear 76T Ver.2, model number 3RAC-SG4876/V2, offers a reliable mix of smooth engagement and long service intervals. It is a straightforward upgrade for focused drivetrain tuning.

Stable performance under load

With its 48 pitch tooth form, this spur is made to maintain consistent contact and reduce slop in the gear train. That stability helps when you are tuning for predictable handling.

Fitment notes and application

The 76T spur suits many standard RC installations. Ensure correct spacing and secure mounting hardware during installation to get the best life from the gear.

What checks should I do after fitting the spur?

After installing, rotate the drivetrain by hand to check for binding, verify mesh under tension, and run a short test at low throttle to confirm there are no abnormal noises.

Does tooth count affect motor load?

Yes. Changing spur tooth count alters torque load on the motor and affects acceleration and top speed. Match spur and pinion to your motor and battery setup to avoid undue strain.

Any tips for long service life?

Keep the gear free of grit, check for burrs after impacts, and maintain correct mesh and lubrication. Replace if you notice rounded or chipped teeth to protect the pinion.
