20T Silent Speed Aluminum Pinion Gear for 48 Pitch (JCO2106)

Silent Speed 20-Tooth Aluminum Pinion Gear for 48-Pitch Systems from JConcepts is a precision-machined pinion designed for 48P RC racing transmissions. Installed at the top of the transmission, it drives the spur gear to transfer power from the motor and set the gear ratio, influencing speed and torque on the track. Designed for smooth, quiet operation with a consistent gear mesh, it helps deliver reliable performance during races.

Machined from aluminum for durability, the 20T pinion offers concentric, tight tolerance mesh for predictable adjustment and reduced gear noise. It uses a durable 3 mm set screw that accepts a 1.5 mm hex wrench and is laser-etched to clearly indicate size. This pinion ranges from 18 to 38 teeth, providing precise tuning for 48-Pitch configurations in RC cars and trucks, helping racers dial in speed and torque with dependable mesh.
