This aftermarket main shaft is supplied as a single alloy component intended for use with the Tamiya TT02 platform and serves as a direct replacement for the factory TT02 main shaft while maintaining the original chassis geometry.
Suitable for TT02-series drivetrains that employ a central main shaft, the part is designed for plug-in replacement and does not normally require chassis modification. Verify shaft length and gearbox layout on your TT02 before installation.
Installation follows standard TT02 gearbox disassembly and inspection procedures. Replace the shaft as part of routine drivetrain servicing to correct wear or endplay, then confirm free rotation and correct gear and bearing alignment prior to running.
