Tamiya 84210 - TA05 Gold Aluminum Bulkhead Replacement  [84210]

Replace the Resin Case with a Gold Aluminum Bulkhead

The Tamiya 84210 - TA05 Aluminum Bulkhead is a metal upgrade to the stock resin gear case, finished in gold for a striking look and improved wear resistance. Its aluminium construction helps reduce friction and extend the service interval of drivetrain parts.

Tight Tolerances for Consistent Drive Feel

This bulkhead has precision-machined surfaces to ensure consistent gear engagement and greater strength under load. The reduced flex compared with resin helps maintain predictable handling through laps and practice runs.

Compatibility Tips and Installation Advice

Designed to fit most TA05 variants, this bulkhead is not compatible with the front section of TA05-IFS models due to their special suspension geometry. Installation is normally straightforward and does not require altering the chassis.
