Just a note on the Bilsteins... You'd be best purchasing from a dealer who has them in stock and ready to ship. When we ordered ours, it took two months for them to get off back order. It's usually more of a month wait. Check out the vendors section of this forum and send messages to some vendors asking if they have them in stock. I've seen some great prices for Bilsteins here on the forum.
I ordered my from Kolak but did have to wait about 3 weeks to get them. It was a special for $279 shipped for all four. I lifted my jeep 4" two weeks later and can't use my rears anymore. I have them (5100s) for sale for $125 shipped for both They are for a 0-2in lift so should fit yours with no problem.
