Koswork 32P M0.8 28T Lightweight Hardened Steel RC Pinion Gear 5mm Shaft - KOS03000-28

The Koswork KOS03000-28 is a 32P M0.8 28-tooth hardened steel pinion gear designed for RC car drivetrains running a 5mm motor shaft. Built from lightweight hardened steel, this RC pinion gear is engineered to handle the stress of high-torque applications while keeping rotational mass low. The included high-torque set screw ensures a firm, secure fit on the motor shaft, reducing the risk of slippage under load. If you're sourcing a reliable 28T pinion for your build or replacing a worn gear, the KOS03000-28 is a direct, no-fuss solution.
