Product Benefits:

Rubber shielded bearings add sealed protection for dirt, dust, debris, outdoor running, and mixed-surface RC use.
Best choice when contamination protection matters more than the lowest possible rolling drag.

Reason to Purchase: Choose rubber shielded bearings for dusty, dirty, outdoor, off-road, or debris-prone RC use because they provide more contamination protection than low-drag metal shielded bearings.

Fitment Note: Confirm your Kyosho OEM/model number before ordering. Bearing sizes are included only where source-backed; otherwise they remain marked as not currently verified.
