The Serpent SER401791 wheelhub is made for the Project 4X PRO family. Supplied as left and right units, it represents a practical replacement or upgrade to refine rear-end behaviour.
The three-point configuration helps distribute cornering forces so the rear end behaves more predictably. That design supports steadier throttle application and cleaner exits.
This hub is compatible with the Project 4X PRO EP (SER400032) and installs using the usual RC toolset. Follow standard fitting practice and check fastener torque after initial running.
