I must admit im confused. So does the maximizer use bearings between the out drive shaft and cup or is it just metal to metal contact like the plastic stockers and Nova cups?

One thing holding me back from the novas is that im worried that the left/right outdrive shafts will develop slop over time due to cup wear. I just replaced my rear stock plastic diff cup after becoming concerned about the excessive play caused by wear. Or am I just paranoid
