Hey bro based on your introduction off road addict. I would recommend the super lift 4" kit. But I would concentrate on getting you armor plating squared away first. The factory skids were an option so you need to check that you have them and not the plastic ones. Then 4xguard sells the armor to fill the gaps of the stock plates all the links can be found on the XK-Parts link found in my sig and your welcome message. If money is an issue the rough country 2" spacer lift is a great option to get you started on the trails while you purchase armor and save up for the SL. JBA UCA's will help with any lift you put on. I do not recommend going over 2" with out the front diff being lowered. Right now only the SL and rusty's 4" kit drop the diff to correct the CV angles and the JBA UCA's correct the ball joint angles.
