Is your Jeep a Rubicon? What size of tires do you plan on running?

 

I installed an OME kit in May on our 07 2-dr. Went very smooth. We've put about a 1,000 miles on it now and everything seems fine. As far as what you should plan on...I'd go ahead and get the adjustable front/rear Track bars. They're not that expensive and you really should center your axles after you put the lift on because it's going to be more lift than you anticipate. I'd also go ahead and get a set of rear adjustable sway bar links. Move the original rear sway bar links to the front. That'll keep your sway bar where it needs to be. If you don't like the way it handles after the install, then you can consider adjustable control arms, etc. to fine tune.

 

I've had my OME for a little over a month on Unlimited. I got OME HD and had adjustable track bars installed with absolutly no issues... I think if you go with this and don't plan on doing much off road you are fine. If more off road new rear sway bar links, move rear to front.
So if you want to be safe and do everything at once:
OME HD
Adjustable Track Bars
Rear Sway bar links

Not sure exact how much but if you do install yourself, you should be able to get this for less than $1,200, just a ruff guess....
