Track-Focused 85T Spur for Stable Drive

The 3Racing 48 Pitch Spur Gear 85T suits drivers aiming for consistent throttle response and minimal drivetrain vibration. It is compatible with many standard RC platforms where precise gear engagement is required.

Key Points to Note

Tooth Count: 85T to improve torque and give smoother acceleration feel.
Pitch: 48 pitch to match a broad range of pinions commonly used in models.
Material: Constructed to resist wear from repeated track sessions.

Setup and Tuning Tips

Fit this spur when you need a more controlled launch or when testing gear ratios for corner exit. Regular checks on mesh and fastener torque will keep gearing reliable.

Is the 3RAC-SG4885 easy to swap during race day?

Yes, it is a straightforward replacement when the pinion pitch matches. Keep a small tool kit and spare screws for quick changes between heats.

Will this gear change handling balance?

Altering spur size affects engine load and acceleration characteristics, which can change weight transfer and traction behaviour. Test settings incrementally.

How often should I inspect the spur for wear?

Check tooth faces after every few race sessions or if you detect noise or slippage. Replace if significant wear appears to avoid damage to the pinion.
