Tamiya 10308 JR Aluminum Shaft Stopper - Precision Mini 4WD Component  [10308]

Tamiya 10308 JR Aluminum Shaft Stopper Overview

The Tamiya 10308 JR Aluminum Shaft Stopper is a compact, precision part for Mini 4WD builders who want a more stable drivetrain. Intended for Mini 4WD and Mini 4WD Pro cars, it clamps onto 72mm hex shafts while remaining incompatible with Super X/XX chassis.

Design and chassis fit

This aluminum stopper is engineered to give a secure hold on the shaft, limiting unwanted movement during fast runs. Its precise fit works with a broad selection of Mini 4WD layouts, making it useful for hobbyists and racers seeking consistent handling across different track types.

Race day benefits

Although modest in appearance, the Tamiya 10308 plays a key role in reducing shaft slip and improving power transfer. That stability helps keep lap times predictable and vehicle control reliable when tweaking racing setups.
