The GPM TXM010/13MM wheel hex is a precision aluminium unit intended to strengthen the wheel to hub interface on the Traxxas X-Maxx 1/8. Its increased 13mm section improves contact stiffness and load distribution under impact and high torque conditions.
This component is produced to provide a more rigid mounting point than standard plastic hexes, reducing radial and axial movement at the wheel flange. The result is more consistent wheel alignment and reduced wear on the mating surfaces during aggressive use.
