A ceramic sealed bearing kit for the Arrma Senton 4x4 3S helps upgrade this RC truck by replacing worn bearings with high-performance ceramic units, delivering smoother rotation and longer-lasting reliability.

Because bearing sizes can vary by model, production date, and installed hop-ups, it's important to confirm compatibility with the exact Senton 4x4 3S configuration before purchasing. The sealed design helps resist dirt and moisture to support consistent performance over time.
