Racing-Focused Spur: 3RACING 48 Pitch 66T Ver.3

The 3Racing 48 Pitch Spur Gear 66T Ver.3 is intended for drivers who need repeatable gearbox performance. Its tooth profile and manufacturing tolerance help maintain steady gear mesh under race conditions, aiding predictable throttle control and lap-to-lap consistency.

Fitment Notes for Tuners

Designed for 1/10 scale race platforms, this spur requires a matching 48 pitch pinion and straightforward mesh setup. Fine-tune pinion position and shims to eliminate backlash while avoiding excessive preload on bearings.

Performance Considerations

When used in competition, expect the 66T to influence acceleration and top speed depending on pinion choice. Check mesh under load, monitor tooth wear between events, and service the gearbox to preserve reliable performance.

Use a 48 pitch pinion of appropriate tooth count to reach desired final drive; ensure pinion runout is minimal to avoid premature wear in high-RPM runs.
Set a snug mesh with minimal axial play: use feeler or shim adjustments, verify smooth rotation under load, and secure fasteners with thread locker where required.
Inspect teeth for chipping, clean debris, check bearing play in the gearbox and re-evaluate mesh after each event to maintain consistent performance.
