Kyosho Mini Inferno 37mm Titanium Main Shaft by GPM TMIF1237  [TMIF1237]

Titanium Main Shaft for Kyosho Mini Inferno

The GPM TMIF1237 is a titanium main shaft produced for the Kyosho Mini Inferno platform, supplied as 1 pr. It is a direct replacement part intended for the Mini Inferno transmission assembly where the main shaft locates the spur and pinion interaction and supports the differential or gearbox components.

Use this shaft when replacing worn or bent originals, or when adjusting drivetrain tolerances during tuning. Installation is straightforward: remove the transmission cover, extract the existing shaft with its retaining clips and bearings, fit the new shaft ensuring proper seating in the existing bearings, and secure any circlips or set screws as per the chassis standard. Verify bearing fit and gear mesh before final assembly.

As a tuning item, this titanium shaft provides a stiffer and more wear-resistant alternative to some stock steels, helping maintain consistent gear alignment under frequent use; however, confirm compatibility with your Mini Inferno gearbox layout and existing bearings before purchase.
