Tamiya 10308 JR Aluminum Shaft Stopper - Mini 4WD Reliability Part  [10308]

Tamiya 10308 JR Aluminum Shaft Stopper Details

The Tamiya 10308 JR Aluminum Shaft Stopper is a neat upgrade for Mini 4WD pilots wanting steadier shaft behaviour. Built for both Mini 4WD and Mini 4WD Pro cars, it is designed to sit on 72mm hex shafts and is not compatible with Super X or XX chassis types.

Compatibility and fitment

This aluminium stopper gives a firm clamp to reduce play on the shaft during high speed runs. Its accurate machining makes it suitable for a wide range of Mini 4WD setups, delivering dependable fit across common configurations.

On-track impact

Rather than a flashy mod, the Tamiya 10308 helps lock the drive components in place so power transfer stays steady. That clarity in drivetrain response can help drivers tune handling and braking points more effectively.
