Koswork 64P 45T Aluminium Thin Lightweight RC Pinion Gear - KOS03004-45

The Koswork KOS03004-45 is a 64P 45-tooth aluminum pinion gear designed for use in 1/10 and similarly scaled electric RC cars running a 64-pitch drivetrain. Machined from lightweight aluminum, this thin-profile pinion is suited to competition and high-performance RC builds where reducing rotating mass on the motor shaft can help drivetrain efficiency. The 45T tooth count places it toward the higher end of the gearing range, making it a useful choice when you need to increase top speed on a track with longer straight sections.

Key Features

• 64-pitch (64P) tooth profile — must be paired with a matching 64P spur gear for correct mesh
• 45-tooth count for higher top-speed gearing compared to lower tooth pinions in the same pitch
• Machined aluminum construction keeps weight low while maintaining durability under race conditions
• Thin lightweight design reduces rotational mass on the motor shaft
• Straight-cut tooth profile standard for electric RC drivetrains

Compatible With

• Any electric RC car or buggy running a 64P (64 pitch) spur gear
• 1/10 scale electric touring cars, buggies, and stadium trucks with a compatible motor shaft diameter
• Commonly used with 540/550-size brushed and brushless motors — confirm shaft diameter before fitting
