Lifted XJ Cherokees
2.5 inch lift
This sized lift is going to require something to help with reducing vibes from the driveshaft. I would suggest a transfer case drop. You don't really need an slip yoke eliminator until you get to about 3.5 inches or more. The SYE is quite a bit more expensive to have installed. You should also look into longer shocks since you are now extending the current ones 2.5 inches more than before.
