Tamiya DT03 Aluminium Wheel Joint by GPM DT3039  [DT3039]

Wheel joint for DT03

This aluminium wheel joint is an RC-scale replacement part produced by GPM for use with Tamiya DT03 chassis layouts. It functions as a direct-fit wheel connection component intended to replace the original wheel joint on DT03-based 1/10 scale models, providing a metal alternative to the stock part.

The component is designed to locate at the wheel hub interface and to work within the DT03 wheel assembly. Installation is performed in the vehicle's wheel area and typically requires removal of the wheel and access to the hub to swap the joint, after which wheel alignment and mounting should be checked for correct seating and free rotation.

In setup and tuning, a metal joint like this is used to reduce play at the hub and to provide a consistent mounting point for wheel alignment adjustments. It is presented as an aftermarket hop-up for maintenance, repair, or incremental tuning on DT03-based models rather than a performance exaggeration.
