3Racing F109 spur gear for tuned race drivetrains

The 3Racing F109 64 Pitch Spur Gear 107T is produced for use with the F109 chassis where precise tooth engagement matters for lap-to-lap consistency. The 64 pitch 107 tooth geometry supports consistent mesh stability, helping to reduce transient lash and improve throttle response during high load shifts.

Technical highlights for performance tuning

  • Compatibility: Engineered to align with F109 mounting and shaft spacing to minimise fitment variables.
  • Precision Engineering: 64 pitch with 107 teeth provides close tooth contact and predictable load distribution across the gear profile.
  • Durability: Manufactured to withstand repeated race cycles while maintaining tooth form and engagement quality.

What mesh tolerance should I aim for on a race setup?

Aim for a minimal but even clearance across the tooth face to avoid binding while keeping backlash low. Verify under load and after initial bedding in.

How does tooth count affect tuning choices?

Tooth count shifts final drive ratio; a 107T spur will require corresponding pinion selection to reach target acceleration or top speed, allowing fine tuning of gearing steps.

Any setup tips for endurance or sprint events?

For endurance, monitor wear and run slightly conservative pinion sizes; for sprints, optimise pinion choice for peak power while confirming cooling and motor temps remain in range.
