Tamiya 42309 37T One-Way Aluminum Pulley for RC Touring Cars  [42309]

Refining Drivetrain Efficiency

The Tamiya 42309 - 37T Aluminum One-Way Pulley is designed to replace the weaker plastic spool and tidy up power delivery in your touring car. The aluminium unit helps reduce drivetrain flex and can sharpen handling in medium-speed corners.

Why Aluminium Works Better

Aluminium offers superior resistance to wear and, with the HL coating, lowers internal friction for steadier torque transfer. That makes it a reliable pick for hobbyists who demand smoother, repeatable performance lap after lap.

Wide Chassis Compatibility

This pulley fits a range of Tamiya platforms such as the TRF419, TRF419X, TRF418 and TA07, plus other cars set up with a direct coupling or spool. Its broad fitment helps you upgrade multiple cars with the same part.
