Product Benefits: This HPI sealed bearing kit gives Micro RS4 a rubber shielded bearing refresh for contamination resistance, maintenance, and consistent RC rebuild value. Rubber shielded bearings add sealed protection against dirt, dust, and debris for bashing, rally, street, track, or off-road use as applicable.

Reason to Purchase: choose rubber shielded bearings when dust, dirt, debris, parking-lot grit, street dust, and longer maintenance intervals matter more than the lowest possible rolling drag of metal shielded bearings.

Fitment Note: Match each included bearing size to the removed factory bearing, press bearings in squarely, and check for smooth movement before running the RC model.
