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

Alloy middle shaft joint for TT-02

This is an RC-scale alloy middle shaft joint produced for the TAMIYA TT02 platform and supplied by GPM under part number TT2315. The component serves as a direct replacement for the center driveline coupling on TT-02 style layouts where a machined alloy joint is preferred for durability and alignment stability.

Installation is straightforward for experienced hobbyists: the joint mounts between the transmission output and the center driveshaft assembly, replacing the stock plastic or composite coupling. Basic hand tools and access to the vehicle's center tunnel are required, and attention to shaft alignment and fastener torque will minimize drivetrain binding.

In setup and tuning, this alloy joint is used to reduce play at the middle connection and to maintain consistent shaft alignment under load, which can aid in predictable handling and drivetrain feedback during setup runs. It is an RC-scale aftermarket part intended for repair, reinforcement, or incremental upgrade of TT-02 drivetrains.
