Ouch! That suspension lift is expensive! Awesome choice though! Calmini puts out everything you need with some instructions, but if you have trouble there is always ZUKIWORLD!! I'm pretty sure you'll have to do some fender trimming to fit some 31 inch badboys on there, but its no big deal. Once it's in, check for rubbing and remedy where nessesary. I have no experience with Rocky Road's body lift, but if you are up for it, there are cheaper alternatives to buying a kit!
