4" lift

If u go trail riding trust me you will have to trim and cut bend the pinch welds in the front fender.
Now if u keep it street only then NO

I just never have had an issue. I go wheeling (trail and climb, dirt, and sand)quite often air down to around 20 and still have not had any rub or scuff issues.

What kind of fuel milage loss are you guys getting with 35/12.50r17 or the 315/70r17s??? I'm debating on going that big I don't want to lose the last little bit of milage I do get

Definitely plan on changing your gears I went with Yukon 4.56 gears front and rear.
I don't have a Programmer bc I can't find one that supports 5.4 2V. And my rig is a 03 Eddie Bauer.
Gas wise it does good in town but on interstate 65+ forget it.
Granted if I had a Programmer I'm sure it would make a difference.

I run 285/70r17 right now and around town with fresh oil I'm getting 15mpg highway I'll get around 19-20 depending on driving conditions. So if I go any bigger you guys think I should re gear? It has 3.73 in it now. I really wanted to go with a bigger tire maybe a true 33x12.50 or a 305/70r17. I have about 3 inches of lift on it with coil overs and spacer kit. Coil overs are nice cuz I can level it out really nice and adjust the spring rate so I'm not so bouncey
