TT-02 Alloy Middle Shaft Joint TT2315 for TAMIYA TT02 by GPM  [TT2315]

Heavy duty alloy middle coupling for TT-02

This middle shaft joint is made for the TAMIYA TT02 platform and offered under part number TT2315. It replaces the standard centre coupling on TT-02 style drivetrains where a metal joint is chosen to increase longevity and alignment stability.

Fitting requires basic disassembly to access the centre tunnel: the joint mounts between the transmission output and the centre driveshaft and takes the place of the OEM plastic or composite coupler. Simple hand tools are usually enough, and correct shaft alignment plus consistent fastener torque will reduce drivetrain binding.

Used during setup and tuning, the alloy joint removes slack at the central connection and helps maintain consistent shaft alignment under load, aiding drivability and predictable feel. It is an aftermarket upgrade intended for repair or incremental reinforcement of TT-02 drivetrains.
