32P 28T Pinion Gear, 5mm Bore (CSE010006506)

32P pinion gears, 28 teeth, offered in a 5mm bore version, are precision‑machined aluminum gears finished in Castle Green. They’re designed to mesh with spur gears in RC powertrains and are a common choice for monster trucks.

Machined from aluminum and finished with Castle Green anodizing, these pinions stay lightweight and resist corrosion while delivering solid performance. The 28‑tooth size provides a balanced mix of torque and drive speed when paired with compatible spur gears, and the 5mm bore variant ensures straightforward mounting on standard motor shafts.
