Koswork 32P M0.8 23T Lightweight Hardened Steel RC Pinion Gear 5mm Shaft - KOS03000-23

The Koswork KOS03000-23 is a 32P M0.8 23-tooth hardened steel pinion gear designed for RC cars running a 5mm motor shaft. Made from lightweight hardened steel, it strikes a balance between durability and reduced rotating mass, making it a practical choice for competition and high-use club racing builds. The high-torque set screw ensures a secure, rattle-free fit on the motor shaft without the need for additional locking compounds.
