You do some minor cutting on the Procomp lift. I installed mine about a year ago on my 2010 fx4. You have to cut a little piece on the drivers side that the stock crossmember bolts too. To put it back to stock you would have to have a bracket made or you may be able to by one somewhere to reinstall the stock crossmember. as for putting it back to stock, im sure it can be done and i know there are some that have done this. Lot of work though.
