What's a cheap,easy way to lift my jeep?

I have been doing a lot of reading and I dnt understand much with spacers, shackles and all. I just really want for the looks I have some decent fat tires, and wanted the jeep look a little lifted not planing to off- road at all, were can I get something to put in the springs to look a little taller? Those kits from pepboys work? And if so what are they called? Thanks a bunch
