Clean Engagement for F109 Setups

The 3Racing F109 64 Pitch 105T Spur Gear - 3RAC-SG64105 is aimed at enthusiasts who tune gear mesh for smooth power delivery in the F109 platform. The 64 pitch spacing helps keep contact consistent lap after lap.

Optimised Tooth Count for Balance

Featuring 105 teeth, this spur offers a usable compromise between acceleration and high speed. It makes small ratio adjustments possible without large jumps in behaviour, which suits track tuning and gearing experiments.

Built for Service and Fit

Designed to slot into the F109 drivetrain, this spur gear is an easy swap for those updating worn parts or trying alternative gearing. Regular inspection and correct mesh setup will keep it running reliably.

Can I use this spur with different pinion sizes?

Yes, changing pinion teeth adjusts final ratio. Keep pinion and spur pitch matched at 64 pitch and check mesh to avoid premature wear.

Is a 105T spur common for F109 setups?

105T is a common choice for drivers who want finer steps in gearing. It lets you fine tune top speed versus acceleration without large jumps.

What should I check before race day?

Verify mesh clearance, check for burrs on teeth, confirm secure mounting, and run a quick idle test to listen for any abnormal noise.
