Description
Designed for 48-pitch RC transmissions, the JConcepts Silent Speed 48-Pitch 21-Tooth Pinion Gear is a precision-machined aluminum pinion that transfers motor power to the transmission, shaping the gear ratio and drive feel on the track.
For racing use, it features a durable 3mm set screw that accepts a 1.5mm hex wrench for secure mounting. The gear is machined for high concentricity to ensure a smooth, consistent mesh with the spur gear, contributing to quieter operation and reliable tuning. It is laser-etched to indicate size for quick identification and is offered in 18 to 38 tooth options, including 21T.
