The Tamiya 3RACING M4WD-38/GO gold aluminium shaft stopper gives Mini 4WD models a firmer drivetrain mounting for more consistent performance. Built for hobby use and race preparation, it helps tame unwanted shaft movement.
This aluminium stopper clamps the drive shaft to limit lateral play and improve power transfer to the wheels. It fits a wide selection of Tamiya Mini 4WD chassis, so it can be used across several kit types without major modifications.
By stopping the shaft from slipping, the part reduces variable friction and supports steadier lap pacing. Racers running high speeds or tight layouts will find the stability gains most noticeable.
