Race-Tuned 3Racing 3RAC-SG4880/V2 Spur Gear

The 3Racing 48 Pitch 80T Spur Gear, model 3RAC-SG4880/V2, is designed with competitive setups in mind to deliver predictable engagement and consistent power transfer. It supports fine tuning of gear ratios and mesh for optimising acceleration and top speed across race conditions.

Professional Notes for Setup

  • Precision Design: Consistent tooth spacing helps maintain repeatable mesh and reduces drivetrain lash during aggressive throttle application.
  • Durable Material: Manufactured to handle frequent tuning and sustained high load without rapid degradation.
  • Wide Compatibility: Suits a variety of 48 pitch chassis layouts, letting racers experiment with different pinions and ratios.
  • Improved Power Transfer: Refined engagement reduces energy loss in the driveline for cleaner throttle response.

How should I choose a pinion to match this 80T spur?

Select a 48 pitch pinion that achieves your target ratio while checking motor timing and RPM range; small pinion changes allow precise lap time tuning.

What mesh tolerance is recommended for racing?

Aim for a snug mesh with a slight clearance to avoid binding; verify under load and recheck after the first few runs to stabilise wear patterns.

Are there tuning tips for longevity under race use?

Rotate pinion options, monitor tooth wear, keep bearings free of play, and adjust mesh rather than forcing tighter engagement to extend service life.
