Tamiya M4WD-38/LB Light Blue Aluminum Shaft Stopper  [M4WD-38/LB]

Quick intro to the Tamiya M4WD-38/LB

The Tamiya Mini 4WD Aluminum Shaft Stopper in Light Blue, model M4WD-38/LB, is made for hobbyists who want a reliable way to lock the drive shaft in place. It secures the shaft to reduce play and keeps the drivetrain running smoothly while adding a corrosion resistant anodized finish for everyday use.

Fit and compatibility notes

This aluminum stopper fits a broad range of Tamiya Mini 4WD models and provides a snug clamp that reduces unwanted movement during sprint runs. Its light construction keeps added mass to a minimum so lap times and acceleration remain unaffected. Common compatible chassis types include MS, MA, and AR, among others.

Track performance benefits

On tight circuits every small stability gain matters. The shaft stopper helps maintain correct drive shaft alignment and prevents slippage under load so power reaches the wheels more consistently. That translates to steadier cornering and fewer mid race issues from drivetrain play.
