Race focused spur gear 3RACING 3RAC-SG6475

The 3RACING 3RAC-SG6475 64 pitch 75T is a precision spur intended for racers and tuners who need consistent tooth engagement when optimising gear ratios. Its tooth profile supports repeatable mesh adjustments during setup sessions.

Setup and Compatibility Notes

The 64 pitch profile offers fine increments for centre distance tuning and allows closer mesh without increased risk of interference when set correctly. Verify pinion pairing and gearbox spacing to ensure correct alignment.

Use in Competitive Tuning

Due to its predictable engagement, the spur is suitable for iterative testing of acceleration and top speed trade offs. Keep a log of mesh settings and track conditions to compare performance changes between runs.

What pinion sizes pair well for testing?

Select pinions that maintain correct centre distance while varying tooth count; small step changes reveal torque and top speed effects. Keep consistent mesh when comparing runs.

How to document mesh for repeatable setup?

Record pinion tooth count, centre distance measurement, and a brief note on running surface and battery state. This lets you correlate mesh settings with lap time differences.

Recommended checks after high power runs?

Inspect spiral and face wear on teeth, confirm no loosening of grub screws, and check for heat-related discoloration. Replace if wear affects mesh consistency.
