Installation & Model Notes

Rubber Shielded Bearing Kit Compatibility (Dusty / Outdoor On-Road):

  • Model: Serpent Medius X20 FWD 1/10 EP Touring Car (#400043)

  • Scale: 1/10 Touring Car (190mm)

  • Fuel Type: Electric (EP)

  • Vehicle Type: On-Road FWD Touring Car (Front-Wheel Drive)

  • Chassis: Medius X20 FWD '21 Carbon Touring Chassis

  • Terrain: Dusty on-road asphalt / outdoor parking-lot running

  • Release Date: 2021

Benefits:

  • Sealed protection helps block dust and grit that kills bearings early.

  • Ideal when your touring car sees outdoor running or less-than-clean surfaces.

  • Strong upgrade path when you want longer service intervals.

Reason to Purchase:

  • If your Medius X20 FWD runs outdoors (dusty asphalt, parking lots), rubber seals help keep contamination out for longer-lasting smoothness and fewer bearing failures.
