Koswork Mod 1 M1 16T Aluminium Lightweight RC Pinion Gear 5mm Shaft - KOS03009-16

The Koswork KOS03009-16 is a Mod 1 16-tooth aluminum pinion gear designed for RC cars running a 5mm motor shaft. Built from lightweight aluminum, this pinion is suited to competition and performance builds where reducing rotating mass in the drivetrain matters. The included high-torque set screw locks the gear securely onto the shaft, helping to prevent slippage under hard acceleration. If you're sourcing a Mod 1 16T pinion gear for a 5mm shaft RC drivetrain, the KOS03009-16 is a direct fit solution from a brand known for precision machined drivetrain components.
