Kyosho Mini Inferno 47mm Main Shaft Graphite Centre GMIF1237 by GPM  [GMIF1237]

Main shaft description

This aftermarket main shaft from GPM is intended for Kyosho Mini Inferno models and is supplied as one pair (1pr). The design combines a graphite centre with alloy end fittings to secure alignment where the shaft meets the gearbox and driven components. The 47mm dimension indicates the sealed length used in Mini Inferno drivetrains.

Fitment warning: the part is suitable for Kyosho Mini Inferno variants. Always confirm the existing shaft length and end fitting profile on your model before fitting, as correct mating with gearbox hubs and couplers is required. This is a model-scale component for hobby use.

How to install: remove the rear gearbox cover and extract the original shaft per the vehicle service routine, then install the replacement making sure alloy ends locate properly in the gearbox supports. Replace any worn bearings or seals discovered while servicing to protect the new shaft.

Tuning notes: upgrading to a graphite-centred shaft with alloy ends can help preserve straightness under load and may reduce rotational slack compared with worn stock shafts, useful for routine maintenance or modest tuning focused on drivetrain response.
