Aluminum outer join for TT-02 performance

This RC-scale aluminum differential outer joint fits TAMIYA TT-02 differentials and is identified by part number TT02-13104-RD. The red anodized aluminum component replaces the standard plastic outer cup to provide a more positive interface at the differential output, helping to reduce unwanted flex under typical driving loads.

Fitting follows common differential servicing steps: open the differential housing, remove the existing outer cup, press the aluminum outer joint on the output stub, confirm seating and rotational clearance, then refit the housing. Check screws for correct torque and ensure free rotation across steering angles before use.

As an aftermarket upgrade this part changes how loads transfer at the outer output, so re-check gear mesh and lubrication after installation and monitor for play during the first running sessions.

What are the main benefits of this aluminum outer joint?

It improves rigidity at the differential output, reduces deformation compared to plastic, and can offer a crisper driveline feel under load.

Is the part a direct replacement for stock cups?

Yes, it is intended as a direct replacement for the TT-02 outer cup, but always verify seating and clearances during installation.

Any special break-in recommendations?

Perform a short initial run and then re-check for play and correct gear mesh; minor adjustments during the first few runs help ensure long-term reliability.
