18T Silent Speed Aluminum Pinion Gear for RC Vehicles (JCO2104)

Silent Speed 18-tooth aluminum pinion gear for 48-pitch RC transmissions is a precision-machined pinion designed to deliver smooth power transfer and quieter operation in race-ready RC cars and trucks.

Machined aluminum ensures concentric mesh for a consistent gear engagement, and it includes a durable 3mm set screw that uses a 1.5mm hex wrench for secure mounting. The gear is laser-etched to indicate size and pitch, part of the Silent Speed line, and is available in sizes from 18 to 38 teeth to help dial in gearing on the track.
