Koswork 48P 18T Aluminium Thin Lightweight RC Pinion Gear - KOS03001-18

The Koswork KOS03001-18 is a 48 pitch 18-tooth aluminium pinion gear designed for use in RC cars running 48P drivetrain setups. Machined from aluminium rather than steel, this pinion gear is noticeably lighter than standard options, which can help reduce rotating mass in the drivetrain. The 48P pitch and 18T tooth count make it a specific, purposeful choice for competition and club-level RC racing where gear selection and drivetrain efficiency matter.

Key Features

• 48 pitch (48P) tooth profile for compatibility with 48P spur gears
• 18-tooth count suits common mid-range gearing configurations in 1/10 scale RC cars
• Aluminium construction reduces weight compared to standard steel pinion gears
• Thin, lightweight profile designed to minimise rotational inertia in the drivetrain
• Part number KOS03001-18 for straightforward reordering and cross-referencing

Compatible With

• RC cars and buggies running 48P pitch drivetrain systems
• 1/10 scale electric RC vehicles using 48P spur gears
• Compatible with motors using a standard pinion bore — confirm bore diameter matches your motor shaft before fitting
