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

Graphite main shaft summary

This GPM aftermarket main shaft is made for Kyosho Mini Inferno owners and is supplied as a single pair (1pr). The shaft pairs a graphite centre section with alloy end fittings to preserve alignment where the shaft meets the gearbox and driven components. The 47mm figure refers to the sealed length used in Mini Inferno drivetrain assemblies.

Fitment advice: the part is intended for Kyosho Mini Inferno variants. Confirm your vehicle's existing shaft length and end fitting style before swapping, since the interfaces must match the gearbox hubs and couplers. This component is designed for model use only.

Installation notes: remove the rear gearbox cover and extract the original main shaft following your model's service procedure, then insert the GPM shaft ensuring the alloy ends seat correctly in the gearbox supports. Inspect seals and bearings during the service interval and replace any worn items; when end interfaces match, the shaft is a direct replacement.

Tuning effect: replacing a worn steel centre with a graphite-centred shaft and alloy ends can help keep the shaft straighter under load and may reduce rotational play compared with tired stock parts, making it a useful routine maintenance or minor hop-up option for improved drivetrain feel.
