Tripp, my BFG KM2 35's measure 34.5 inches tall. I had Pro Comp MT 33's that were 32 in. tall.

The 37" KM2's measure 35.5, they are the worst. The Km2 40's are true to size.

There ya go...a 37 with the leverage of a 35.5.

Km2 is a great tire.

C'mon guys...show me someone with new km2 on a 17x8 with a center to center tire height.  I had always heard this but mine have always measure within .5 or .6 of stated height. 

Maybe someone meant 36.5 and not 35.5, I included their spec sheet which was spot on for my measurement.

Finally did it...pulled the trigger on RK 3.5" X factor w/ 2" Bumpstop, fox ats stabilizer and bilstein 5100's. Now just waiting for them to come in  //popcorn//. Just have a few more questions.

1. Looked into the cost to have the Artec Armor welded  //:hlp//... is it overkill or is it a pay now so you dont have to pay later?
2. Which 35" tire.... Big difference in weight from what I want Trail Grappler(80lbs) to something like a KM2(67lbs).... where as the KM2 37" is still lighter at 74lbs but then we have the leverage issue.  Is it safe to the run the trail grappler when it weighs more than most 37's?
3. Anything else you guys recommend or think is essential to add now?

Again, I want to thank everyone for all the help so far...this is a great community, especially for some one to learn alot that has no experience...me!

An 80 lb tire for a 35" tire seems to be absolutely insane to me. That's just stupid heavy! For every pound of rotating weight you can remove, makes the car think you removed 10 pounds. So if the tire is 10 pounds heavier x 4 tires that's like loading your Jeep up with 400 lbs! Not that great for anything I can think of... well maybe an anchor. I would consider a tire that weighs less and if that means going up a size... be that as it may. Change wheeling style until you build axles.

regarding the Truss.... 100%... the JK with the wide axles are prone to bending the axle tubes also be sure to have the C gussets done as that is another weak link on the axle. If you can't afford to do the regear now, consider getting the truss now. You don't want to regear bent axles in a year from now.

That's why  I went with the Duratarack tires. Much lighter and super quiet. So far they are great in DurhamTown. I will update after Hale Mountain.

I still have the Duratrac's I love them. Not great in heavy mud, but if them made them in a 37" they would be mounted to my rims already. For a 34.5" they wrap the rocks fantastic.

Thank you everyone for your help. I know I'm really beating a dead horse here but as I'm waiting for my lift to get here I cant help but think once I get 35's Ill just want 37's. A little background this is my DD and only used on trails basically every other weekend but nothing to crazy. My question is what would you recommend now that I'm 95% thinking 37's... Truss, gusset and sleeve and I should be worry free for DD? Again sorry to beat a dead horse but Im finding it hard to justify saving for 60's since I dont beat it.

I wouldn't even consider 37s for a daily driver, but many others have and do.  Seth drove his everywhere everyday on 37 BFG's. 

Planning to regear?

Stay with 35's on a Dana 30. Truss it and Gussets. You will have no problems on trails with that set. Add lockers and your golden.

You had 33's and 35's

I have done the measurements on the 37's. Ask @Metro , he has them and were the ones I measured. I'll try and dig up a picture of mine and his side by side, it's a noticeable difference.
