This replacement main shaft is specified for Kyosho Mini Inferno gearboxes and is produced from aluminium alloy at a 47mm nominal length to restore drivetrain geometry and extend service life compared with worn stock shafts.
Fit and installation: the component is intended to locate into standard Mini Inferno transmission layouts when used with original mating parts. Access requires transmission housing removal; refit using correct bearing seating practice and specified torque for retaining hardware to preserve alignment and minimise runout.
Service notes: installing an aluminium main shaft focuses on durability and consistent gear mesh rather than delivering direct power increases. Check shaft runout and bearing condition during reassembly to avoid introducing vibration into the drivetrain system.
