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

Rear universal joint shaft for Mini Inferno ST

This rear universal shaft serves as a direct replacement for the Kyosho Mini Inferno ST chassis, MIF-ST02/HD. It transmits power to the rear wheels and is made to resist the typical wear seen in frequent hobby use.

Labelled heavy duty, the part is suited to higher stress cycles and repeated running compared with stock components. In practical tuning it helps reduce driveline twist and preserve setup geometry under load.

Fitment is straightforward for experienced builders: remove the rear drivetrain cover, withdraw the existing shaft per the chassis instructions, and install the replacement ensuring correct engagement with the gearbox output and rear hubs. Confirm free rotation and proper seating before use and inspect regularly for play and wear.
