37's on an Unlimited with a 4" Lift anyone?

Have an Unlimited X package with a 4" lift, 4.88 gears and currently running 35's. Would 37's be too much for this set up?

How much lift did you actually get out of the 4" lift? Supposedly you can fit 37's under a 4" lift. But if 4" is how much actual lift you got, then you would more than likely have rubbing issues. You would more than likely need to trim the pinch seam in the front of the rear wheel well, and look for rubbing elsewhere.

I am running 37" tires myself with a 4" Teraflex lift. But in the rear I have a pair of 2.5" BB spacers and in the front I have a set of ACOS Pros. So when all said and done I am about 7.25" total suspension lift. After some bumpstop tweeking I am now able to run and flex the 37" tires without any adverse rubbing issues and I haven't done any trimming.

here is my friend. Rubi on 37's with Teraflex 4" lift. He said he really got more like 4.5" out of it in the front with the AEV bumper, close to 5" in the rear.

Very nice jeep! I have my pinch welds trimmed already and I have 2" spacers for front and rear (if needed) but I don't have adjustable control arms only adjustable track bars.

Any more advice on this subject? I'm in the same boat as SickBoy and would like to know more.

Also is there a good writeup anywhere on trimming the pinch seams?

a saw and a steady hand. Cut the pinch seam at an angle. I would suggest them giving the metal a nice coat of primer and/or paint.

Doing so won't mess with the 'structural' integrity of that area?

Also I have an angle grinder and a dremel. Which would you recommend?

You will not loose the structural integrity of the area by cutting back about 1.5" at an angle. I use a angle grinder with a cutting wheel as well as a 90* grinder wih a cutting wheel to trim corners of the body and bumpers. I then will finish them off with a file if need be on plastic mostly.
