3Racing 3RAC-PG4837 competition grade 48 pitch pinion

Engineered for precise gearing, the 3Racing 48 Pitch 37T Pinion Gear uses 7075 aluminium for solid mechanical properties while retaining a low mass. The hard coating improves the pinion's resistance to surface wear, supporting repeatable drivetrain behaviour across race days and testing sessions.

Racing focused features

  • Material Selection: 7075 aluminium chosen for its high strength-to-weight characteristics.
  • Hard Coating: Provides improved wear resistance to help the pinion sustain service in demanding conditions.
  • Tooth Accuracy: Consistent tooth form supports predictable mesh and efficient torque transfer for tuned setups.
  • Application: Ideal as a tuning or replacement part in 48 pitch competition gearboxes.

What should I check when fitting this pinion?

Ensure correct backlash and tooth contact pattern, secure the set screw to the motor shaft, and confirm the motor mount does not allow movement under load.

Is this pinion suitable for high torque applications?

When used in a 48 pitch system with proper mesh and a sound mounting setup, the 7075 aluminium pinion with hard coating is appropriate for higher torque motors common in competitive builds.

How do I inspect the pinion after track use?

Check the tooth profiles for smoothing or nicking, inspect the set screw seating, and verify the coating remains intact on the contact surfaces.
