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.
