Koswork 48P 20T Aluminium Thin Lightweight RC Pinion Gear - KOS03001-20

The Koswork KOS03001-20 is a 48 pitch, 20 tooth aluminium pinion gear designed for use in 1/10 and similar scale electric RC cars running 48P drivetrain setups. Cut from aluminium rather than steel, it sheds weight from the motor output shaft — a meaningful consideration in competitive and performance-focused builds where rotating mass affects throttle response. The KOS03001-20 suits a range of brushed and brushless electric RC cars that use the 48P standard pitch, making it a practical option when replacing a worn pinion or selecting a specific tooth count to dial in your gear ratio.

Key Features

• 48 pitch (48P) tooth profile matches the most common standard used in 1/10 scale electric RC cars
• Aluminium construction reduces rotating mass compared to a standard steel pinion gear
• Thin, lightweight profile keeps the gear compact without sacrificing tooth engagement
• 20 tooth count allows gear ratio tuning — lower tooth counts suit torque and acceleration, higher counts suit top speed
• Machined aluminium finish for consistent tooth geometry and reliable mesh with compatible spur gears

Compatible With

• Electric RC cars and buggies running 48P pitch gearing
• Compatible with most 1/10 scale brushed and brushless motor setups using a standard 48P spur gear
• Suitable for use where the motor shaft diameter matches the pinion bore — confirm bore size before fitting
