The six-lug disk kits use the original hub and therefore the original ball bearings can be used.

The five-lug kits use an integrated hub/rotor that was designed to use roller bearings.

If you are going with a six-lug kit and your bearings are serviceable there would be no reason to replace them. Going with a five-lug kit you may have no choice but to convert to rollers.
