Kyosho Mini Inferno ST Rear Universal Shaft - Heavy Duty by 3Racing MIF-ST02/HD  [MIF-ST02/HD]

Rear universal shaft for Mini Inferno ST

This rear universal shaft is an RC-scale replacement part intended for the Kyosho Mini Inferno ST chassis, offered by 3Racing as MIF-ST02/HD. It serves as a direct drivetrain component to transfer power to the rear wheels while resisting common wear modes in hobby use.

The unit is described as heavy duty, which in practice means it is built for higher duty cycles and repeated on-track stress compared with standard stock pieces. In routine tuning it is used to reduce flex and maintain consistent driveline geometry under acceleration and corner loads.

Installation is straightforward for experienced hobby technicians: remove the rear drivetrain cover, extract the existing shaft following your chassis manual, and fit the replacement ensuring correct engagement with the gearbox output and rear hubs. Check for proper seating and free rotation before track use. Regular inspection for play and wear is recommended as part of standard RC maintenance.
