Track-Focused Spur for the F109

The 3Racing F109 Spur Gear 64P 103T - 3RAC-SG64103 is aimed at drivers who want consistent drivetrain behaviour. Matched to the F109 chassis, this spur keeps power delivery even and repeatable under load.

Accurate Tooth Profile for Better Control

The 64 pitch, 103 tooth configuration yields a tighter tooth engagement that helps reduce slop in the drivetrain. That accuracy supports tighter control when setting up gear mesh and throttle modulation for tight circuits.

Compatibility and Easy Installation

This spur is cut to fit the F109 chassis and mounts with common hardware, making installation straightforward. Its robust design stands up to regular running and basic servicing between sessions.

Can I use this spur with different pinion sizes?

Yes, you can pair it with various pinion sizes to change gearing ratios; just check mesh and ensure the motor clearance is adequate for the chosen pinion.

Is 103 teeth common for racing spurs?

A 103 tooth spur sits in a range that balances acceleration and top speed. It works well with 64 pitch pinions for fine tuning gearing steps.

Any tips for installing the spur?

Set a conservative initial mesh, then run the chassis briefly and recheck mesh after bedding in. Use thread lock on mounting hardware if required by your setup.

How do I inspect for wear?

Look for rounded or chipped teeth, uneven wear patterns, and burrs. Replace the spur if tooth form deteriorates to avoid damage to the pinion.
