Mopar Lift kit question

I have an 08 two door Rubicon. I was at the dealer today and picked up the wrangler mopar accessories catalog. I've been back and forth trying to decide what I want to do. My first question pertains to the 4.5" lift they advertise. Does this kit come complete with everything to run 35's? will I have to change anything ie: gears, cv's, drive shafts etc? or is it safe to say I can have the dealer install this lift with 35's on and life is good with no other add ons to make this run smooth? I'm the only stock Jeep with the guys I wheel with, everyone is running 35's and up and so far the stock Rubicon does well, but life every red blooded male you always want bigger and better. I've also been contemplating just running a 2 or 2.5 inch lift and rolling with 33's, because from what I've read it is a lot more simple with less sress on parts. I do not want to have any issues with my warranty or my dealer blowing me off if something breaks because of mods. I like to wheel but i'm also not into thrashing my rig like my buddies as it is new and its my daily driver. I fear that 35's will compromise too much and cause too much wear and tear. What are your thoughts?? thanks...

Jeep or die.

you named just about everything that is recommend, will need new gears if you want it to have any power at all going up a hill. Will need new driveshafts at some point, mine went out after 5k miles of flat driving. Would not recommend going over 2.5" lift and 33"s unless your willing to dump some cash on other things. Ive had my 35's for about 10k miles now and love them, but did have to upgrade the gears and driveshaft to make it enjoyable.

I did run the 35's on it for about 5k miles without the gears and the 4.10 are just barrelly tolerable with a 6spd. Pulling anything, head wind and even small hills would bog the engine.

The Mopar lift is the Rubicon Express lift with the stickers removed. Go to RE's website and pick up the full specs there.

Thanks guys, I think that pretty much sold me on just going with a small 2.5" and some good 33's. Cash isn't the issue, but I'm not into replacing perfectly good drive shafts and other parts just to fit tires a few inches bigger. Like I said, the rubicon is a beast in stock form compared to most vehicles, 2.5" good 33s good driving skills (most important) should keep me going and happy. thanks for the info. any more opinions is welcome.

you will be able to go more places with your rubicon on 33s than your friends jeeps on 35s if they are not locked.

that is the combo I am using. Leaving in 15 minutes to get the wheels and tires mounted. You can go 35's if you want with the 2.5 lift. It rubs only at full flex and if you aren't an extreme wheeling kind of guy you will be fine.

The Unlimited Rubicon comes with LT255/75/17 which is a 32.05" tall tire according to BF Goodrich site. Through other sites, discussions, and friends I have heard that the Rubicon can tolerate 35" tires with no problems. It is when people go up to 37" and beyond that the OEM Dana 44 axles start showing problems. I know this might not be exactly what you guys were discussing but I thought it might give some examples of tolerances on given axles, tire size, and OEM set up.
