Tamiya 84210 - TA05 Gold Aluminum Bulkhead Upgrade  [84210]

Stiffen Your TA05 with a Gold-Finish Aluminum Bulkhead

The Tamiya 84210 - TA05 Aluminum Bulkhead is a direct replacement for the stock resin gear case, crafted from gold-finished aluminum to increase toughness and cut friction losses. Its solid construction gives a neat visual upgrade as well as longer service life for club track and practice sessions.

Precision Machining for Reliable Gear Operation

Built with tight tolerances, this aluminum bulkhead fits the TA05 chassis precisely to reduce play and wear in the drivetrain. The machined aluminium body helps keep gear alignment stable under load, lowering the chance of friction related drag during spirited driving.

Compatibility Notes and Straightforward Fitting

This unit fits the majority of TA05 chassis variants, but it is not suitable for use on the front of TA05-IFS models because of their unique suspension layout. Installation is simple and usually requires no extra modifications, making it a practical upgrade for most hobbyists.
