Product Benefits: This HPI rubber shielded bearings kit uses sealed bearings for Nitro RS4 3 RTR maintenance where dirt, dust, and debris protection is important.
Reason to Purchase: Choose rubber shielded bearings when protection and durability matter more than metal shielded bearings with the lowest possible rolling drag. They help protect against dirt, dust, and debris during off-road running, bashing, parking-lot use, and longer maintenance intervals while supporting reliable drivetrain service.
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.
