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

47mm aluminum main shaft for Mini Inferno

This RC replacement main shaft is made for Kyosho Mini Inferno models, sized at 47mm and formed from aluminum alloy to replace worn or damaged stock shafts while maintaining drivetrain geometry and improving long term durability.

Fit and installation: the shaft is intended to fit standard Kyosho Mini Inferno gearboxes when used with stock mating components. Removal of the transmission housing is required to access the shaft; refit following original bearing seating and torque recommendations. Use correct bearings and retaining hardware to preserve alignment.

Tuning notes: swapping to an aluminum main shaft is primarily a maintenance and durability choice rather than a power upgrade; it helps retain consistent gear mesh and alignment during setup changes. Always check shaft runout and bearing condition when reinstalling to avoid introducing drivetrain vibration.
