The Tamiya 3RACING M4WD-38/GO gold aluminium shaft stopper provides a dependable method to reduce drive shaft play in Mini 4WD cars. It is a pragmatic upgrade for racers and hobby builders aiming for more repeatable performance.
This aluminium stopper secures the drive shaft to limit unwanted movement and improve torque delivery to the wheels. Its fit covers many common Tamiya Mini 4WD chassis so it is useful across a range of kit types.
By preventing shaft slippage and lowering friction variance, the stopper helps produce smoother lap times and steadier handling. The benefit is most evident on layouts where drivetrain precision affects corner exit and top speed.
