Koswork 64P 28T Aluminium Thin Lightweight Pinion Gear - KOS03004-28

The Koswork KOS03004-28 is a 64 pitch, 28 tooth aluminium pinion gear designed for use in 1/10 and similarly scaled RC cars running 64P drivetrain setups. Machined from aluminium rather than plastic, this thin, lightweight pinion gear reduces rotational mass in the drivetrain, which suits builds where minimising unsprung or rotating weight is a priority. The KOS03004-28 is a direct swap for worn or damaged 64P pinions and is also a popular choice when fine-tuning gear ratios for specific track conditions or motor pairings.

Key Features

• 64 pitch (64P) tooth profile for compatibility with standard 64P spur gears used across many 1/10 RC touring cars, pan cars, and similar classes
• Aluminium construction keeps weight lower than steel pinions while offering better durability than plastic alternatives
• 28 tooth count suits a range of motor and spur gear combinations — useful when adjusting overall gear ratio for track conditions
• Thin profile design is suited to tighter gear spacing requirements found in many competition-oriented RC car platforms
• Sold individually as a standalone pinion for targeted replacement or gear ratio adjustment

Compatible With

• RC cars and buggies running a 64 pitch spur gear
