There will a lot more to it then what those kits are coming with that I know of.
You will need some sort of high steer set up, extended brake lines, Anti wrap bar if you are going to do any wheeling. SYE and new driveshaft and there is probably a little more that I am forgetting.
I think if done right you will end up spending over a grand to accomplish it.
I really like what they do to a jeep but I would not skimp on anything in the process.
