Dial in drivetrain feel with the 3Racing 48P 72T gear

The 3Racing 48 pitch spur gear with 72 teeth is a practical component when refining gear ratios for better throttle modulation. It offers consistent tooth geometry for dependable meshing during aggressive use.

Key points for 3Racing spur gear choice

  • Precision Engineering: The 48 pitch, 72-tooth layout helps maintain correct tooth contact to smooth out power transfer and lower mechanical noise.
  • Durable Material: Constructed to stand up to frequent running and the stresses of spirited track sessions.
  • Compatibility: Designed to fit models that accept a 48 pitch spur, giving you a straightforward upgrade or replacement option.
Use a feeler gauge or a small shim and a screwdriver to set proper backlash, then lock the gearbox and rotate to confirm smooth movement.
Yes, provided the rest of the drivetrain matches the 48 pitch specification; brushless motors do not change the required gear pitch.
Light lubrication on gear bearings and occasional inspection is enough; avoid excess grease that can attract debris between teeth.
