Track-focused 3Racing pinion for better drivetrain response

The 3Racing FFEX 0.8 pitch 21T pinion delivers tighter engagement for the KIT-FFEX chassis, helping to cut drivetrain play and improve throttle predictability. Built to consistent tolerances, it is a practical choice for both weekend racers and club competitors.

What the 21T Pinion Provides

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

Can I use this with a high torque motor?

Yes, 0.8 pitch is common for moderate to high torque builds, but ensure correct mesh and inspect for wear more often with very powerful setups.

How should I check gear mesh?

Use a strip of paper between pinion and spur, tighten grub screw, then rotate to ensure a snug but free mesh. Recheck after a short run.

Is any modification needed for fit?

This pinion is made for KIT-FFEX geometry and normally fits without machining. Confirm shaft diameter and grub screw alignment before final fitment.
