Koswork 64P 41T Aluminium Thin Lightweight RC Pinion Gear - KOS03004-41

The Koswork KOS03004-41 is a 64P pitch, 41-tooth aluminium pinion gear designed for use in competitive RC racing applications. Machined from lightweight aluminium, this thin-profile pinion is aimed at racers who want to reduce drivetrain rotating mass without sacrificing precision gear engagement. The 64P pitch is a standard used across a wide range of 1/10 and 1/12 scale electric touring cars, pan cars, and similar competition-class RC vehicles, making it a practical option when speccing or rebuilding a gearbox for track use.

Key Features

• 64P (64 pitch) tooth profile for precise mesh with compatible 64P spur gears
• 41-tooth count suits mid-to-high speed gearing ratios depending on motor and spur combination
• Aluminium construction reduces rotating weight compared to steel pinions
• Thin lightweight design targets competitive racers looking to minimise drivetrain inertia
• Machined format provides consistent tooth geometry for reliable power transfer

Compatible With

• 1/10 scale electric touring cars using 64P pitch gearing
• 1/12 scale pan cars using 64P pitch gearing
• Any RC vehicle drivetrain specced for 64P spur gears
• Note: shaft bore size should be verified against your motor shaft diameter before fitting
