Kyosho Inferno MP 7.5 Titanium Universal Main Shaft for Middle Gear Box by GPM TMP75237  [TMP75237]

Universal Titanium Main Shaft for MP7.5

This titanium universal main shaft is a scale RC drivetrain spare designed for the Kyosho Inferno MP 7.5 platform, intended to replace the stock shaft in the middle gear box assembly. The package includes the shaft pair and the mounting screws required for the middle gear box, so you receive a direct drop-in part that keeps the RC nature of the vehicle explicit and avoids any real-vehicle implications.

In technical terms the part serves two practical roles: it provides a stiffer, lighter rotating element compared with standard steel shafts, and it maintains alignment between the spur/pinion train and the middle gear box. When planning a tune, consider this shaft as a component to reduce rotating inertia and improve drivetrain consistency rather than as a performance "upgrade" claim; its benefits are realized when combined with correct gearbox shimming and bearing condition.

Installation requires access to the middle gear box, removal of the old shaft and associated hardware, and reassembly using the supplied screws. Check the gearbox for worn bearings or damaged spline surfaces before fitting the new shaft to ensure smooth operation. This component is presented as an RC-scale spare part, compatible with the MP7.5 drivetrain layout stated in the product title.

For builders and hobbyists maintaining or refreshing an Inferno MP 7.5 drivetrain, this titanium shaft provides a direct replacement option that focuses on alignment and durability within RC-scale gearboxes.
