Description

Overview

The HPI Racing 15-Tooth Pinion Gear is a precision-cut 1.0 module motor pinion designed for use with 5mm motor shafts. With 15 teeth, this pinion offers slightly more torque-biased gearing compared to a 16T option — ideal for high-grip tracks or aggressive acceleration.

This OEM-quality gear delivers smooth mesh and reliable performance, perfect for fine-tuning your drivetrain ratio.

  • 15-tooth count
  • 1.0 module (1M) pitch

Performance Benefits

  • Slightly more torque, slightly less top speed than 16T
  • Smooth power transfer
  • Long-lasting durability
  • Tunable gear ratio option

Usage Notes

Verify proper mesh with the paper-test method during installation. Apply thread-locker to the pinion grub screw and gear grease to the gear teeth.
