Wheel Hexacon 440131 for Serpent Mini Spyder Monster truck RTR EP (SER440001)  [SER440131]

Wheel hex details for Mini Spyder

The Serpent 440131 wheel hexacon is intended as a direct spare part for the Serpent Mini Spyder Monster truck RTR EP (SER440001). It secures the wheel on the hub and transmits propulsion and braking loads during model running.

Fitting on the compatible Mini Spyder platform is done by removing the wheel, checking the current hex for signs of wear, sliding the 440131 replacement into position on the axle seat, and reattaching the original retention system. Maintain the chassis' specified torque settings and confirm true seating to avoid wheel runout affecting steering response.

In terms of setup, the wheel hex is a small but critical part of the drivetrain; any play or damage can introduce wobble or inconsistent grip. Regular inspections and replacing the hex when wear appears will protect bearings and fasteners and keep handling consistent.
