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

Replacement wheel hex for Mini Spyder

This Serpent 440131 wheel hexacon is an RC-scale replacement designed specifically for the Serpent Mini Spyder Monster truck RTR EP (SER440001). It positions the wheel on the hub and carries torque and braking forces during model operation.

Installation is straightforward on the compatible Mini Spyder chassis: remove the wheel, inspect the current hex for wear or deformation, slide the 440131 hex onto the axle seat, and secure using the vehicle's original retainer. Use the existing hardware and torque recommendations, and check for concentric seating before final tightening to prevent wheel runout from affecting handling.

From a setup perspective, the wheel hex is a small but important drivetrain link; excessive play or a damaged hex can cause wheel wobble and inconsistent traction. Regular inspection after several runs and timely replacement when wear appears protects bearings, wheel nuts, and helps retain predictable handling.
