This two piece 12x10mm aluminium hex adapter is offered as an aftermarket upgrade for Tamiya Wild Willy 2 WR-02 chassis that use the 12x10mm wheel interface. The set is supplied as 2pcs to provide matched wheel-hub connection options.
The component provides a metal-to-wheel interface designed to limit wear on the original hex and help retain correct wheel alignment under normal running loads. It is intended as a practical replacement or basic durability upgrade for model-scale RC use.
Installation is carried out by seating the adapter in the hub hex recess and securing it with the hub's existing retention hardware. No electronic or chassis modifications are required to use this part.
