27T Silent Speed Pinion Gear for 48 Pitch Applications (JCO2113)

27-Tooth Silent Speed 48-Pitch Pinion Gear by JConcepts is a precision-machined aluminum pinion designed for 48-pitch RC transmissions. It drives the transmission by meshing with a compatible spur gear, delivering a precise gear ratio, smooth power transfer, and a quieter ride on the track. The pinion includes a durable 3 mm set screw that uses a 1.5 mm hex wrench and is laser-etched to indicate tooth count for quick identification on or off the vehicle.

Machined for concentricity, the Silent Speed pinion provides a tight, consistent mesh that helps maintain repeatable acceleration and top speed. Available in sizes from 18 to 38 teeth to support a wide range of gearing for 48-pitch applications, it carries the JC branding for easy recognition in the pit. Designed for quiet operation and reliable performance, it’s a practical upgrade for racers tuning their RC transmissions.
