This replacement main shaft fits Kyosho Mini Inferno models and is manufactured from aluminium alloy at a 47mm length to replace worn stock components while preserving correct drivetrain geometry and improving service lifetime.
Fit and installation: intended for use with the stock Mini Inferno gearbox and mating components in typical assemblies. You will need to open the transmission housing to remove and fit the shaft; reassembly should follow original bearing seating and torque recommendations and use proper retaining hardware to maintain alignment.
Service and tuning: choosing an aluminium main shaft is a durability and maintenance decision more than a performance modification. It supports steady gear mesh during setup changes — check shaft runout and bearing condition on reinstall to avoid drivetrain vibration.
