How deep are your pockets?...LOL. Yea, upgraded driveshafts, axles, gears and I have heard that theres nothing lower than 5:13's. I'd say with 6 inches of lift you would still bottom out like crazy.

I could be wrong on this stuff, but you will have to upgrade EVERYTHING that I said and maybe more. There's a guy on here with a red X that has 38.5's and gears, 6inch lift, and shafts and I say it wont flex as good as my stock X with 35's on no lift.

I don't mean anything bad about this red JK...badass ride sitting on 18's and 38's but the tires sit really close to everything. Its to nice to wheel and get muddy.

Its like us hotrodders say...."speed costs money, how fast do you wanna go?. Its the same with this.


Let us know what you really wanna do with this...Mall Crawler? 50/50 offroader? or Rockcrawler only?

An engine.

Then after you snap your axels... an entire new suspension and drive train too.

Ive seen it done on a 2 dr with fender flares removed and dana 60's put in with lockers and a blown out cadilac motor.

If you do stuff that can use all that then go for it and please post some vids...

"What would it take to run 40" tires?"

Deep pockets! Rigs with 37's can be built for a whole lot cheaper and are very capable. Although Off Road Evolutions Jeep with 40's is SICK!!!

I think that Teraflex has a 6" lift that can be used to run 40" tires. I would get this, and a super 44 kit when superior comes out with them, and 5.38 gears when they come out as well at the minimum. Eventually though you would probably want to upgrade to some Dana 60 axles, like the Rock Jock ones from Currie.
