Tamiya 53291 - TA03 Race-Grade 15T Aluminum Pulley  [53291]

Track-focused 15T pulley for the TA03 chassis

The Tamiya 53291 - TA03 aluminum pulley is a race-focused replacement for the TA03, using a 15-tooth profile to sharpen power delivery and reduce drivetrain slack. It is precision cut to provide consistent meshing with your gear train.

Why aluminium improves drivetrain performance

Aluminium offers a good stiffness-to-weight ratio that reduces rotating inertia while resisting distortion. The tight tolerances of the machined pulley lower friction and slow the onset of wear compared with standard plastic components.

Installation tips to keep things reliable

During fitment, verify shaft alignment and the pulley seating to avoid side load on bearings. Periodic checks after hard sessions will catch loosened fastenings early and prolong service intervals.
