Racing Grade Spur for F109 Drivetrains

The 3Racing F109 64 Pitch 105T Spur Gear - 3RAC-SG64105 is engineered for competitive tuning, delivering consistent meshing geometry for F109 chassis gear trains. Its 64 pitch profile reduces play between teeth for improved repeatability during laps.

Tuning Benefits of 105 Teeth

A 105 tooth count lets technicians make fine incremental ratio changes when swapping pinions, useful for optimising acceleration versus top speed in race conditions.

Serviceability and Compatibility Notes

Designed for direct replacement in F109 assemblies, the spur supports standard mounting hardware. For best results set backlash precisely and inspect contact pattern after initial run in.

What mesh clearance is recommended for racing use?

Aim for minimal visible clearance with no binding. After tightening gearbox fasteners recheck mesh under load to ensure the contact patch remains centred.

Should I run a break in procedure for a new spur?

Run progressive laps at moderate power to seat teeth, then inspect contact and adjust mesh. This reduces early wear and helps stabilise performance.

Any adjustments when changing pinion size with this spur?

When altering pinion tooth count recheck final ratio and torque delivery. Small pinion changes can require setup tweaks to maintain handling balance.
