Tamiya 53988 Ball Differential Pulley 37T Competition Grade  [53988]

37-tooth ball pulley from Tamiya 53988 for crisper drive feel

The Tamiya 53988 ball differential pulley is made to bring crisper, more consistent power transfer to your RC model. The 37-tooth design focuses on steady engagement and predictable drivetrain reactions during throttle changes.

What it improves on the car

This pulley helps reduce drivetrain lash and gives better modulation under acceleration, which benefits both timed runs and spirited weekend driving. Compatibility with many Tamiya chassis makes it a flexible upgrade.

Practical installation tips

Fit the pulley with correct shims and check gear mesh to avoid premature wear. Swap it in to replace ageing parts or to fine-tune handling for tighter cornering and smoother exits.
