I have a 2007 JKU and want to install the TF 2.5 Coil Lift. What are the problems or issues I will be running into? Do I need to change out the control arms and track bars? Are there any other mods that I shouldpaln for? The JKU has Duratrac 33s on MB Cahos 5 Wheels, and the XRC MOD Bumper with Bull bar. Will be adding the end caps and the Smitybilt X2O 8 Comp Winch when they come in. Also plan on the XRC rear bumper and tire carier. I don't want to get inot this and find out there are more things that need to be done. Wantt to do it all at one time, budget allowing of course.
