The Tamiya 53474 - TA04 Aluminum Center Pulley is a direct-fit upgrade for TA04 cars using a centre one-way unit. It fits on the spur gear shaft to give a firmer interface and reduce component wear under racing conditions.
Constructed from solid aluminium, this pulley replaces softer stock parts with a tougher option. The untreated finish is practical and durable for day-to-day track use.
The unit comes with one centre pulley, three 3mm grub screws and an Allen wrench so you can fit it straight from the box. The hardware matches common TA04 mounting points for quick changes.
Dimensions are 18mm outer diameter with a 13.6mm pulley tooth diameter. The overall height is 13mm and the pulley height is 7.5mm, designed to sit correctly in the TA04 drivetrain.
