Extra Parts needed?

Planning on getting the rustys 4.5, what i'm wondering is if there is other things that i "need" when getting the lift other than whats included. It says that what you get is all u need but will i be ok driving with just the lift and tires for a while?what should i add after a while?is i absolutely necessary?

what year xj? my guess is ull need a SYE and CV shaft as well.

my jeep is a 99

yea ull definitly need a SYE and cv shaft.

I would get an adjustable trackbar. JIM.

It comes with a TC drop kit so if it works on your jeep more power to ya.
*You may want to get a new steering stabilzer and some new U-bolts before the install. I'm not sure if their springs are designed for pinion angle but you may need shims.
*After the install look into barpin eliminators for your shocks (stops the clankin), longer bumpstops (so your spring will last longer), and upper control arms (for front pinion angle).
