The Serpent SER401791 wheelhub is a purpose-made part for the Project 4X PRO series. Supplied as left and right pieces, it provides a straightforward upgrade to rear-end behaviour on diverse track surfaces.
The three-point mounting spreads loads across the hub to promote consistent tyre contact during cornering. That stability helps drivers maintain line and throttle through exits.
Designed to work with the Project 4X PRO EP (SER400032), this hub installs with basic RC workshop tools and simple hand fitting, making it suitable for club racers and weekend tuners.
