3Racing 3RAC-SG6499 Competition 64 Pitch 99T Spur for F109  [3RAC-SG6499]

Technical Overview for Competitive Builds

The 3Racing F109 64 Pitch Spur Gear 99T is produced to support precise ratio selection and repeatable gear engagement in F109 race vehicles. The 99-tooth geometry yields a fine-grained step for tuning acceleration and top speed while maintaining uniform tooth contact across the engagement arc. The component is intended for direct integration into stock F109 drivetrains with standard mounting interfaces.

Material and Functional Considerations

Manufactured to provide stable meshing under load, the 3Racing F109 spur supports routine race-day tuning practices. The 64 pitch format allows narrower ratio changes compared with coarser pitches, which benefits setups that require incremental performance adjustments. Ensure correct pinion selection and mesh pattern verification during installation to preserve gear life and drivetrain efficiency.

Installation and Setup Notes

Install using established gear mesh procedures and verify engagement over multiple rotations before full-power testing. The 99T spur is suitable for both replacement and planned tuning swaps; monitor adjacent drivetrain components for wear when changing gear ratios to avoid introducing new failure points.
