JConcepts 25 Tooth Silent Speed Aluminum Pinion Gear (JCO2111)

JConcepts Silent Speed 25-Tooth Aluminum Pinion Gear for 48-Pitch RC Transmissions is a precision pinion designed to transfer motor power to the drivetrain while keeping noise to a minimum. Built for 48-pitch systems, it helps maintain a consistent mesh and predictable gear ratios for competitive on-track performance.

Machined from durable aluminum for true concentricity, the Silent Speed pinion delivers smooth, quiet operation on the track. It features a 3mm set screw that accepts a 1.5mm hex wrench and is laser-etched to clearly indicate size and pitch for quick identification on or off the vehicle. Available in sizes from 18 to 38 teeth, these pinions provide flexible tuning options to match different motors and track conditions, all while maintaining reliability.
