Putting a 4" Rough Country lift on my '08 Unlimited. The shop putting it on and 4wd.com have both assurred me that I would not need to change anything in the drive train at this time. I don't plan on doing anything crazy with it right now, just a few mild trails and maybe a little mud. Should i be fine to ride like this? If not on trails or mud, it should be fine as a daily driver still right?
