Racing-focused spur gear guidance for 3Racing 3RAC-SG6486

The 3Racing 3RAC-SG6486 64 pitch 86T spur is intended for tuners who prioritise consistent tooth engagement and predictable drivetrain behaviour. Its 64 pitch profile delivers closer contact geometry that helps reduce variable backlash during hard acceleration and corner exits.

Performance oriented features and considerations

  • Tooth Count: 86T to influence final drive characteristics for tuned setups
  • Pitch: 64 pitch for tighter tooth mesh and improved repeatability
  • Material: High-quality construction aimed at durable service under competitive use
  • Compatibility: Compatible with many mainstream racing chassis using standard spur mounts

How should I approach pinion selection when fitting this spur?

Start from your baseline pinion and adjust incrementally to dial in lap times and motor temperature; small changes in teeth can have noticeable effect on acceleration and top speed.

What mesh settings work best for racing?

Aim for a snug but free-running mesh with no play at the tooth flank; confirm under load and after a short run as seating can change initial clearance.

Any maintenance tips for track reliability?

Regularly inspect tooth profiles and mounting hardware, replace the spur at the first sign of uneven wear, and keep the drivetrain clean to preserve predictable behaviour.
