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

Overview of the graphite main shaft

This aftermarket shaft from GPM is made for Kyosho Mini Inferno vehicles and is delivered as a single pair (1pr). It features a graphite middle section with alloy end fittings to maintain straightness where the shaft connects to gearbox and driven parts. The 47mm length is the sealed measurement used in Mini Inferno drivetrain setups.

Compatibility note: designed for Kyosho Mini Inferno variants. Always verify the original shaft length and end fitting type on your model before fitting, since the coupler and hub interfaces must be compatible. This is an RC-scale replacement component only.

Fitting guidance: access the rear gearbox cover and remove the existing main shaft assembly per your model's service instructions, then slide in the replacement and ensure alloy ends seat in the gearbox supports. Replace any worn bearings or seals encountered during servicing to protect the new shaft.

Performance role: a graphite-centred shaft with alloy ends can reduce lateral flex and free play compared with worn stock components, helping drivetrain responsiveness for routine maintenance or modest performance upgrades.
