Competition-Focused 48 Pitch Spur for Tuners

The 3Racing 65T 48 pitch spur caters to experienced tuners looking for repeatable gear engagement and drivetrain predictability. Suited to a range of 48 pitch platforms, this spur supports accurate ratio changes and stable power transfer, useful when optimising lap times or race-day performance.

Setup and Tuning Considerations

When configuring your gear train, pair the 3Racing 48 pitch spur with a matched pinion to achieve the desired final ratio. Pay attention to mesh and backlash during setup, and verify engagement across the tooth face to reduce premature wear and ensure consistent results between runs.

How should I approach gear mesh tuning for race setups?

Start with minimal clearance and increase slightly until the mesh runs smoothly without binding. Confirm the mesh after a few laps and adjust as needed to compensate for shaft and bearing play.

Which factors influence spur longevity in racing conditions?

Consistent mesh, correct lubrication of associated bearings, and avoiding abrasive contaminants are primary factors. Regular inspection and replacing worn pinions will also prolong spur life under high load.

What should I consider when changing tooth counts for tuning?

Changing the spur tooth count alters acceleration and top speed. Choose a combination of pinion and spur that fits your track demands, and always recheck mesh and motor temperature after making ratio changes.
