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

Rear driveline universal shaft for Mini Inferno ST

This rear universal shaft is an RC replacement designed for the Kyosho Mini Inferno ST chassis, MIF-ST02/HD. It transmits drive to the rear wheels while addressing common wear factors encountered in regular hobby use.

Termed heavy duty, the unit is intended to handle higher stress and repeated sessions compared with original stock pieces. In tuning it reduces driveline stretch and helps sustain consistent geometry under load.

Installation is routine for competent hobby technicians: remove the rear drivetrain cover, pull out the existing shaft following your manual, and fit the replacement ensuring correct engagement with the gearbox output and rear hubs. Verify smooth rotation and proper seating before running and inspect periodically for play and wear.
