Precision Spur Gear for Tuning with 3Racing 3RAC-SG4871

The 3Racing 48 Pitch Spur Gear 71T (3RAC-SG4871) provides a reliable platform for setup changes and ratio experiments. With 71 teeth in a 48 pitch profile, it helps maintain steady engagement and predictable torque flow during spirited runs.

Compatibility and Practical Notes

Designed for models using 48 pitch drivetrains, this spur gear meshes cleanly with matching pinions to reduce binding and uneven wear. It is suitable for drivers who regularly tweak gearing for track conditions and want a consistent reference part.

How do I check correct mesh with this spur?

Fit the pinion and spur, set backlash to a small clearance, then spin the drivetrain by hand to check for smooth contact across the tooth face.

Is the 3RAC-SG4871 suitable for competitive setups?

Yes, it is suitable as a baseline spur for tuning; its 48 pitch form helps keep gear engagement predictable in race conditions.

What should I look for when replacing a worn spur?

Inspect tooth profiles for rounding or chips and verify the mesh with a new pinion before running at full power. Replace if contact is inconsistent.
