HRCSG182R08 - Aluminum 1/8 to 2mm Pinion Reducer Sleeve

This product is a precision aluminum pinion reducer sleeve designed to adapt 1/8″ bore pinion gears for use on 2 mm motor shafts common in smaller RC vehicles. Machined aluminum construction provides a lightweight yet rigid interface between the larger gear bore and the smaller motor shaft, helping maintain proper gear engagement and reduce slippage. Anodized finish helps resist corrosion while ensuring smooth installation on the motor shaft. The compact 10 mm length keeps overall drivetrain packaging tight and compatible with a variety of 1/18 scale conversions. Ideal when you want to expand pinion gear options without changing motor hardware.
