Aftermarket TAMIYA TT02 Middle Shaft Joint TT2315 by GPM  [TT2315]

Durable alloy centre joint for TT-02

This alloy middle shaft joint is intended for the TAMIYA TT02 platform and carries the model number TT2315. It is supplied as an aftermarket replacement for the centre driveline coupling where a machined metal joint is preferred to reduce play and improve alignment stability.

Installation is aimed at hobbyists familiar with basic disassembly: the part fits between the gearbox output and the centre driveshaft, replacing the factory plastic or composite coupler. Basic hand tools and access to the vehicle centre tunnel are required, and careful attention to shaft alignment and correct fastener torque will minimise binding.

In setup and tuning scenarios, this alloy joint is used to minimise movement at the mid connection and to hold shaft alignment under load, which contributes to more consistent handling and clearer drivetrain feedback. It is an aftermarket component for repair, reinforcement or modest performance refinement of TT-02 drivetrains.
