Precision Cut Spur Gear for Racing Use

The 3Racing 48P Spur Gear 72T Ver.2 features a refined tooth form to promote low noise and repeatable performance during race day. Its 48 pitch construction offers a reliable interface with common 1/10 scale pinions, providing predictable torque transfer for drivers tuning final drive ratios. Routine checks and correct mesh will keep the gear running smoothly.

Is this spur suitable for carpet and hard pack tracks?

Yes. The fine 48 pitch teeth suit smoother surfaces like carpet and hard pack, delivering consistent engagement and modest noise levels when meshed correctly.

What signs show I should replace the spur?

Look for rounded or chipped teeth, excessive backlash that cannot be corrected by mesh adjustment, or visible gouging. Replace to avoid damaging the pinion or motor.

Can I use this with brushless setups?

Yes. It is compatible with brushless motors, but ensure your pinion choice suits the motor RPM and torque to keep loads within the gear's capacity.

Any recommended final checks after fitting?

Confirm the mesh across rotation, ensure the spur sits flat on its mounting surface, and verify the motor shaft and pinion are concentric to avoid premature wear.
