Kyosho Mini Inferno Alloy Main Shaft (47mm) by GPM MIF1237  [MIF1237]

Alloy main shaft for Mini Inferno

This is an RC-scale replacement main shaft produced by GPM for the Kyosho Mini Inferno platform, sized at 47mm and manufactured from aluminum alloy. It serves as a drivetrain component intended to replace a worn or damaged main shaft in Mini Inferno models, restoring original geometry and offering a durable alternative to stock parts.

Fit and installation: the part is designed to fit Kyosho Mini Inferno assemblies without modification when used with the stock gearbox and mating components. Basic disassembly of the transmission housing is required to access the main shaft, and reassembly should follow the original torque and bearing seating practices. Use of correct bearings and retaining hardware is necessary to maintain alignment.

Tuning role: swapping to an aluminum main shaft is mainly a maintenance and durability choice rather than a performance upgrade; it helps maintain drivetrain alignment under regular running and supports consistent gear mesh during setup changes. Check shaft runout and bearing condition when reinstalling to avoid introducing vibration to the drivetrain.
