Kyosho Inferno MP 7.5 Universal Titanium Main Shaft - TMP75237 by GPM  [TMP75237]

Titanium main shaft for MP 7.5 middle gear box

This titanium universal main shaft is a scale RC drivetrain spare made for the Kyosho Inferno MP 7.5 platform and fits the middle gear box assembly. The kit contains the matched shaft pair plus the mounting screws for a direct replacement that preserves the vehicle's RC identity without implying real-vehicle use.

Functionally, the component reduces rotating mass compared with standard steel shafts while offering improved torsional stiffness. It helps keep the spur and pinion train aligned to the middle gear box when bearings and shims are correctly set. Consider it a drivetrain consistency component rather than a standalone power upgrade.

Fitting requires removing the middle gear box cover, extracting the old shaft and hardware, and installing the supplied screws with the new shaft. Inspect bearings and spline surfaces before reassembly to prevent premature wear. The part is intended as an aftermarket spare compatible with the MP7.5 drivetrain layout shown in the title.

For workshop maintenance on an Inferno MP 7.5, this titanium shaft provides a straightforward replacement focused on alignment and longevity within RC-scale gearbox assemblies.
