Precision gearing with the 3RACING 64 Pitch 109T spur

The 3RACING 64 Pitch Spur Gear 109T is a value racing component aimed at setup-minded drivers. Its tooth count and 64 pitch profile support consistent mesh geometry and reliable power transfer under race conditions.

Racing-oriented attributes

With 109 teeth, the spur allows fine adjustments to overall ratio for lap time optimisation. The 64 pitch specification improves tooth contact fidelity with compatible pinions, aiding clutch-in behaviour and throttle response tuning.

Integration and setup guidance

Fitment follows standard spur installation procedures; set pinion backlash and use shims to obtain straight engagement. For competitive tuning, validate mesh under load and log any wear patterns to guide pinion changes or differential adjustments.

What pinion considerations apply when using this 109T spur?

Select a pinion that yields your target ratio while preserving at least three to four full threads engaged on the motor shaft; check gear alignment across the face width.

How should I monitor wear during race events?

Inspect tooth profile after heat cycles, note any directional wear and replace if tooth forms become rounded to avoid unpredictable power delivery.

Are there tuning tips for tighter mesh on this pitch?

Use incremental shim adjustments and run brief load tests to settle mesh; document the setting that gives the best compromise of noise, temperature and throttle feel.
