Koswork 64P 31T Aluminium Thin Lightweight Pinion Gear - KOS03004-31

The Koswork KOS03004-31 is a 64 pitch, 31 tooth aluminium pinion gear designed for use in 1/10 and 1/12 scale electric RC cars running 64P drivetrains. Cut from lightweight aluminium, this thin-profile pinion gear keeps rotational mass low, which suits builds where motor response and weight reduction are a priority. If you're sourcing a 64P pinion gear for a competition or club-level electric RC car, the KOS03004-31 slots into the standard 64P gear mesh used across a wide range of touring car and pan car platforms.

Key Features

• 64 pitch (64P) tooth profile for compatibility with standard 64P spur gears used in electric RC touring and pan car classes
• 31 tooth count — a mid-range gearing option suited to balancing top speed and acceleration on typical track layouts
• Aluminium construction reduces weight compared to steel pinions, keeping drivetrain mass low
• Thin lightweight design minimises rotating inertia, contributing to sharper motor response
• Part number KOS03004-31 identifies this as the 31T variant within the Koswork 64P aluminium pinion range
