Upgrade Your Geartrain with Serpent 120159

The Serpent 120159 - 48P 21T Aluminum Motor Pinion Gear is crafted from durable aluminium to reinforce your RC driveline. Its 48-pitch, 21-tooth specification ensures precise gear engagement and predictable power flow for hobbyists refining performance.

Durability Without Excess Weight

Hardened aluminium construction gives the Serpent 120159 pinion good resistance to wear while keeping spinning mass low. The reduced rotational weight helps sharpen acceleration and can decrease energy draw from the battery during normal operation.

Which Cars and How to Fit

Suitable for any model that uses 48-pitch gearing; the 21-tooth option gives a mid-range compromise between speed and pulling power. Check the motor shaft size and set the pinion mesh carefully to avoid premature wear or noisy operation.
