Koswork 32P M0.8 19T Lightweight Hardened Steel RC Pinion Gear 5mm Shaft - KOS03000-19

The Koswork KOS03000-19 is a 32P M0.8 19-tooth pinion gear designed for RC cars running a 5mm motor shaft. Made from hardened steel, this pinion is built to handle the demands of competition and high-frequency running where standard gears wear quickly. The lightweight construction reduces rotating mass without sacrificing durability, and the high-torque set screw ensures the gear stays firmly locked to the shaft under load. If you're looking for a reliable 19T pinion for a 5mm shaft motor, the KOS03000-19 is a straightforward, well-spec'd choice.
