Description
JConcepts Silent Speed 48 Pitch 32-Tooth Pinion Gear (JCO2118) is a precision-machined aluminum pinion designed for 48-pitch RC transmissions. Sitting at the top of the transmission, it sets the gear ratio that drives the drivetrain, with the Silent Speed design delivering a steadier, quieter mesh for race-day performance.
Machined for durability and true concentricity, the pinion is laser-etched to indicate size and pitch. It uses a 3mm set screw that tightens with a 1.5mm hex wrench for secure mounting. Available in sizes from 18 to 38 teeth, Silent Speed pinions offer tuning options to balance speed and torque across different tracks and conditions.
