The Tamiya 3RACING M4WD-38/GO gold aluminium shaft stopper is a compact upgrade aimed at improving shaft retention and driveline consistency. It is useful for hobbyists who want cleaner mechanical performance without complex mods.
Designed to stabilise the drive shaft, this aluminium stopper reduces unwanted shaft movement and helps maintain efficient power transfer from motor to wheels. It is compatible with many Tamiya Mini 4WD chassis configurations.
Fitting this stopper can lower friction spikes and prevent shaft slip, contributing to steadier lap times and more predictable cornering. It is especially helpful on technical or fast sections where drivetrain stability matters.
