Race-ready 3Racing pinion for the KIT-FFEX

The 3Racing FFEX 0.8 pitch 21T pinion is aimed at pilots seeking steadier gear engagement in the KIT-FFEX platform. Precision cut teeth help maintain consistent mesh and reduce slop that can sap performance. A sensible swap for maintenance or incremental tuning.

Principal Specs of the 21T Gear

Pitch: 0.8
Tooth Count: 21T
Compatibility: Designed specifically for the KIT-FFEX chassis
Function: Improves drivetrain performance and precision

Is this the same size as stock pinions?

Tooth count and pitch match common FFEX setups, but check shaft fit and grub screw position to confirm it replaces your stock pinion cleanly.

Does it need special lubrication?

Regular light gear grease on the spur mesh is sufficient. Avoid heavy pastes that can attract debris and cause premature wear.

Will this change gear ratio noticeably?

Tooth count is 21T; only ratio changes if you swap spur size or use a different pinion tooth count. This part keeps the intended ratio while improving mesh quality.
