Others more knowledgeable then I will chime in, but I suggest you continue to research, once you have a basic idea of want you want contact Kolak on this forum. Kolak is a wealth of knowledge and is an excellent vendor who can make sure you get the right lift for your needs.
Personally I ordered am OME HD lift from Kolak. Currently I have 1.25" spacers and I'm running 265-70-17 Cooper Discovery tires. I/m waiting for the lift to arrive. (the wait is killing me)
