Koswork 48P 19T Aluminium Thin Lightweight RC Pinion Gear - KOS03001-19

The Koswork KOS03001-19 is a 48 pitch 19-tooth aluminium pinion gear designed for use with 48P motor and drivetrain setups in competitive RC cars. Machined from aluminium to reduce rotating mass, this lightweight pinion gear is aimed at racers and builders who want precise gear engagement without the added weight of a standard steel pinion. The 48P tooth pitch is a widely used standard in 1/10 scale touring car, buggy, and stadium truck classes, making KOS03001-19 a practical choice for setups that already run 48 pitch spur gears.

Key Features

• 48 pitch (48P) tooth profile meshes with standard 48P spur gears used in many 1/10 scale RC car applications
• 19-tooth count suits a range of motor and speed configurations within typical 48P drivetrain builds
• Aluminium construction reduces rotational weight compared to steel pinions, which can contribute to faster motor response
• Thin, lightweight profile is suited to space-constrained gear boxes where minimising added mass matters
• Koswork part number KOS03001-19 allows straightforward identification when ordering alongside matching spur gears or motor hardware

Compatible With

• RC cars and buggies running 48 pitch (48P) spur gear systems
• 1/10 scale touring cars with 48P drivetrains
• 1/10 scale off-road buggies and stadium trucks using 48P gearing
• Motors with a 3.175mm (1/8 inch) shaft where a 19T 48P pinion is appropriate — verify shaft diameter before ordering
