Koswork 64P 39T Aluminium Thin Lightweight RC Pinion Gear - KOS03004-39

The Koswork KOS03004-39 is a 64 pitch, 39 tooth aluminium pinion gear designed for use in 1/10 and 1/12 scale electric RC cars running 64P drivetrain components. Machined from aluminium alloy, this thin lightweight pinion gear reduces rotating mass compared to standard steel pinions, which can benefit throttle response in competitive racing applications. If you're looking for a 64P 39T pinion gear to suit a touring car, pan car, or similar electric RC platform, the KOS03004-39 is a precise, race-oriented option worth considering.

Key Features

• 64 pitch (64P) tooth profile — must be matched to a 64P spur gear for correct mesh
• 39 tooth count suits mid-to-high gear ratio setups on electric RC drivetrains
• Aluminium construction keeps weight low compared to steel pinion gears
• Thin lightweight profile designed to minimise drivetrain inertia
• Part number KOS03004-39 identifies this specific tooth count within the Koswork 64P pinion range

Compatible With

• Electric RC cars and touring cars using 64P (64 pitch) spur gears
