Koswork 32P M0.8 26T Lightweight Hardened Steel RC Pinion Gear 5mm Shaft - KOS03000-26

The Koswork KOS03000-26 is a 32P M0.8 26-tooth hardened steel pinion gear designed for RC cars running a 5mm motor shaft. Built from lightweight hardened steel, this RC pinion gear strikes a balance between durability and reduced rotational mass, making it a practical choice for competitive and recreational electric RC car builds alike. The included high-torque set screw ensures a secure, slip-free fit on the motor shaft, which is especially important under hard acceleration.
