Hey, so if you put a 3" lift on it, you're gonna need to cut the fenders.
I'd suggest cutting the sway bar, too, for more flex, but that's optional.
If I were you, I wouldn't put 33s on her, because you'll be stuffing them on, pretty much... I'd say 32s should be the biggest you go for that... I also suggest new tires for 🏆winning🏆, haha.
Daily driving with a 3" lift sucks for highway driving. Feels like driving a sail boat, in my opinion.
Also, a lot of people will flip out and tell you to get a longer Trac bar bracket, relocation bracket or adjustable Trac bar, but from my experience, 3" should have the stock one still on to avoid shifting te axle towards the passengers side. If you go higher than 3", that's when is suggest something longer.
Also in my opinion, I'd suggest using full leaf springs and not add-a-leafs, because stock XJ shackles and leafs (especially ones that are 22 years old, haha) tend to rust and sag...
Good luck!!
