Tamiya TT01/TT02 Graphite Main Shaft with Alloy Ends by GPM GTT2B025  [GTT2B025]

Graphite main shaft for Tamiya platforms

This is an RC-scale graphite main shaft finished with alloy ends supplied as 1pc, intended for use on Tamiya platforms where the TT01 shaft form is specified and listed as compatible with TT02 and TT02B in fitment notes. The component combines a graphite central section with machined alloy end fittings to address axial and torsional stiffness in the model drivetrain.

Installation is a direct replacement of the existing main shaft where the stock seating and retaining method match the part; standard disassembly of the gearbox or center transmission is required to access the shaft. Verify end-fit engagement and runout during reassembly and recheck any wheel or spur mesh settings after fitting to maintain proper drivetrain alignment.

In tuning terms the graphite centre limits flex compared with all-plastic shafts while the alloy ends preserve secure connection to outdrives, so the part is used where builders want firmer rotational response and reduced play without changing gearbox geometry. As with all RC parts, confirm compatibility and inspect mating components before extended use.
