I've got a 99xj with pretty saggy rear leafs and I'm running the BF goodrich t/a's that came with it. Im going to need tires before winter and I want to get 30" tires. I also purchased a brush guard which I'm going to install so I'm assuming that'll lower my suspension a little bit too my rear is sagging probably an inch also. I want a little bit of lift but not a lot just so I'll get a nice look with 30s and not like they're too small. I don't want to have to worry about t-case drops and trying to stay cheapish for now so thats why I'm trying to stay mild. Any opinions on A) Tires ( I want A/T's ) and whose lift and how much lift.

If you want dirt cheap just get spacers and shackles...cost like 100 bucks. Your 2nd option would be just a basic 3 inch lift with leaf packs (which you need.if your already sagging)..these 3 inch kits start around 450..you could also make a bastard pack rear with new lift coils..

Go with bfg all terrains...best a/t out there.

Will it look goofy with 3" of Lift like with only 30s

Here is like 5 inches with 30s

Oh wait..I forgot my jeep had a 3in lift on it when I bought it...duh!
Here is 3 inches and 30s on a 98.

Look into OEM up-country new leafs (approx $98 apiece and coils approx $40 piece). It will give you 1.5" of lift. Want another 1" add spacer & shackles.

Will I need to do anything else other than adding the lift parts?

Not really

2" and 30's does all I need it to do

lol...Looks like mine when I first bought it ^^^^^
