Koswork 64P 43T Aluminium Thin Lightweight RC Pinion Gear - KOS03004-43

The Koswork KOS03004-43 is a 64P 43-tooth aluminium pinion gear designed for use in 1/10 and 1/12 scale RC cars running a 64-pitch drivetrain. Cut from aluminium to reduce rotating mass compared to steel pinions, this 43T gear is suited to builds where a lighter drivetrain component is a priority. At 43 teeth it sits at the higher end of the tooth count range for a 64P pinion, making it a useful choice when tuning gear ratios for lower top-end RPM and stronger low-speed torque.

Key Features

• 64-pitch (64P) tooth profile — must be paired with a 64P spur gear for correct mesh
• 43-tooth count for a numerically lower gear ratio, favouring torque over outright top speed
• Aluminium construction reduces weight compared to standard steel pinion gears
• Thin, lightweight profile suited to tight motor-to-spur clearances in competitive RC builds
• Style code KOS03004-43 identifies this specific tooth count within the Koswork 64P pinion range

Compatible With

• RC cars and buggies running a 64P (64-pitch) gear system
• Typically suits 1/10 and 1/12 scale on-road and off-road RC platforms with a 64P spur gear
• Compatible with motors using a standard 3.17mm (1/8 inch) motor shaft — verify your motor shaft diameter before fitting
