Kits are always in stock and ready to ship! For shocks, it depends on your driving style but we usually recommend either the Fox 2.0 Performance shocks if you plan on doing mostly on road driving with some wheeling once in a while, or something like the Falcon adjustable's if you plan on driving more aggressively or take it off-road a lot more. The only driveshaft modification that would be necessary is changing out the front drive shaft if you do plan on doing any off-roading. Once in four wheel drive, the factory front drive shaft takes a beating with the vehicle lifted so upgrading is always recommended, though it is not something you have to do right away for everyday on road driving. Hope that helps answer some of your questions!
