This aluminium front wheel hex adapter is an RC-scale replacement built for TAMIYA DT-03 fitment and intended to mate with GPM optional wheels and tyres. Supplied as a 2pcs set, the adapter incorporates a bearing to promote smoother wheel spin and reduce hub friction versus a standard plastic hex.
Fitment is specific to the DT-03 chassis and this hex is designed around GPM optional wheels and tyres; it is not a universal wheel hex. Installation takes place at the wheel hub, replacing the stock front hex to improve centring and rotational stability.
For setup and tuning the adapter helps preserve consistent wheel geometry through cornering and makes tyre alignment easier when swapping wheel sets, which is handy for routine chassis maintenance and track-side adjustments.
