Mini Inferno Transmission Main Shaft 37mm TMIF1237 by GPM  [TMIF1237]

Titanium Drive Shaft for Mini Inferno Builds

The TMIF1237 is a 37mm titanium main shaft designed for use in Kyosho Mini Inferno transmissions and supplied as 1 pr. It positions the spur and pinion and supports the differential or gearbox internals.

Installation is simple: open the gearbox, remove the existing shaft with its clips and bearings, fit the new shaft into the current bearings, and resecure circlips or set screws per the chassis instructions. Always confirm gear mesh and bearing alignment before sealing.

For tuners, this titanium shaft offers better stiffness and longer wear life compared with some stock parts, helping to preserve gear alignment through frequent running. Check your diff and bearing arrangement for full compatibility prior to purchase.
