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

Precision alloy centre joint for TT-02 drivetrains

The TT2315 middle shaft joint is engineered for the TAMIYA TT02 platform as a precision aftermarket replacement. Manufactured to provide a stiffer centre coupling, it is suited to builders who prioritise alignment stability and long term durability for centre driveline connections.

Installation follows standard practice: the joint replaces the factory centre coupling between the gearbox output and the centre driveshaft. Use basic tools to access the centre tunnel, verify spline engagement, and apply consistent torque to hardware to avoid misalignment and binding.

In workshop tuning, this precision alloy joint reduces axial and lateral play at the mid connection and maintains consistent shaft geometry under load, aiding repeatable handling and predictable drivetrain feedback. It is a professional-grade aftermarket reinforcement intended for repair and incremental performance improvements on TT-02 drivetrains.
