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

Wheel hexacon spare for Mini Spyder

The Serpent 440131 wheel hexacon is manufactured as a direct replacement for the Serpent Mini Spyder Monster truck RTR EP (SER440001). It locates the wheel on the axle and relays torque and brake loads during normal running.

Fitting is simple on the compatible Mini Spyder platform: remove the wheel assembly, compare the old hex to the 440131 for signs of wear, push the replacement onto the hub or axle seat, and refit the original retainer. Keep factory hardware and recommended torque settings, then verify true seating to avoid uneven wheel rotation.

In tuning and maintenance terms, the wheel hex is a small but vital drivetrain component; any looseness or damage can create wobble or erratic traction feedback. Quick routine checks and swapping the hex when wear appears helps preserve bearings, nuts, and overall handling predictability.
