Re: Rocky Road Outfitters Budget Lift for TJ
Well, I don't know about the shock extensions, but I don't think that you'll have a problem with vibration from the BB. I didn't. Most people don't from just a 2" BB, but I have heard a few people say that they did. If so, I'd say a couple of washers worth of TC drop would take care of it.
Make sure you get it aligned after you install it though. Or do it yourself. It's pretty easy. I'm sure you can find how with a search on this board. Sorry, but I'm too lazy to find it for you right now.
Good luck with the lift.
Oh, and you could also do what I'm doing about the shocks if you don't trust the extensions. Just run your stock ones until they explode from over traveling. Then you can justify getting the right length.
