Smart Swap for Better Cornering

The Tamiya 42309 - 37T Aluminum One-Way Pulley is a direct replacement for the standard plastic spool, aimed at improving how the car behaves through medium-speed bends. The aluminium construction helps maintain consistent power delivery during transitions.

Benefits of Upgrading to Aluminium

Moving to aluminium increases component life and, with its HL finish, reduces friction where it counts. That makes gear engagement feel more predictable and reduces slop under load for many setups.

Fits Multiple Tamiya Chassis

Compatibility includes TRF419, TRF419X, TRF418 and TA07 models as well as other cars using a direct coupling or spool. Its fitment breadth makes it a convenient upgrade across several platforms.

How does the Tamiya 42309 affect handling balance?

The stiffer pulley can reduce drivetrain flex, which often tightens the rear end feel and gives a more consistent balance through medium-speed corners.

Are there any setup changes needed after fitting it?

Most cars require no major setup change; check gear mesh and spool alignment after installation and make small trim adjustments to fine tune handling.

Will using this pulley increase wear on other parts?

Not typically. Aluminium reduces deformation, which can lower abnormal wear, but regular inspection of bearings and coupling is advised.
