TAMIYA TT01 Graphite Main Shaft with Alloy Ends by GPM GTT025  [GTT025]

Graphite main shaft for TT01

This is an aftermarket graphite main shaft assembled with alloy end fittings designed for scale TAMIYA TT01 RC chassis. The component combines a graphite shaft body with machined alloy ends to provide a compact replacement part intended specifically for TT01 drivetrain assemblies, described here as an RC-scale accessory only.

Compatibility is limited to the TT01 platform; it replaces the stock main shaft in typical TT01 transmission layouts without introducing new drivetrain geometry. Installation requires aligning the shaft with the existing holders and securing it using the original retaining hardware, preserving the intended assembly positions used in TT01 builds.

In tuning terms this part is used to adjust drivetrain feel: the graphite section helps control torsional response while the alloy ends maintain seating and interface accuracy with bearings and gearbox interfaces. Regular checks on fit and bearing alignment will help maintain predictable transfer of power during track setup and debugging.
