Welcome to the forum, and thank you for your service. Congrats on the new Jeep
First, wave, to every Jeep you see... it's tradition
Second, wheel it stock a few times and find out what you need as far as mods go. Third, prepare to Just Empty Every Pocket....
Modding is addictive, and Jeeps have a million and one options for modding.
The beauty of JK's is that you don't have to lift them much to put on bigger tires. 2.5" is plenty to run 35's.. We just installed a Teraflex 2.5" budget boost on our '07. There is a forum member discount on Teraflex products through Northridge4x4 Jeep Parts Online Store
I think you have to call and ask for Jeffrey to get the discount. If you know some mechanically inclined people and have the right tools, installing a lift is not that difficult, it will take some time tho'.
Spend a couple of days reading the topics on the forum and you'll learn a ton, and have a few laughs and make some friends along the way.
This is a great forum, full of very nice people and some very knowledgeable Jeepers.....
