Introduction to the Tamiya M4WD-38/LB shaft stopper

The Tamiya Mini 4WD Aluminum Shaft Stopper in Light Blue, model M4WD-38/LB, gives racers a compact solution to secure the drive shaft. The anodized light blue finish improves surface hardness and resists wear from regular running and maintenance sessions.

Compatibility and chassis guidance

Designed to suit many Tamiya Mini 4WD kits, this stopper provides a firm hold that reduces unwanted shaft movement at speed. Its low mass design keeps the car nimble while supporting common chassis formats such as MS, MA and AR.

Why use a shaft stopper on track

Keeping drivetrain components aligned reduces friction losses and unpredictable handling. The stopper prevents shaft slip, ensuring smoother power transfer to the wheels and more consistent lap times on club tracks and practice sessions.
