You will need the jack cover if you do not want to mess up the paint at the jack points. Tried it on the back jack point a couple of days after I bought the jeep and it definitely started to dig into the paint and that is why I ordered one. I have not rotated my tires yet but my plan is to jack up the back side with my floor jack with a towel over it and same side front with the OEM jack because of the pinch welds. Switch tires and do the same on the other side. Finally jack up one side of back with my big jack and the other back side with the OEM and swap the tires again.
