I had their 6.5" X series kit, alot of people bash their stuff, but for the price, they are hard to beat. You will definently need an SYE kit, it comes w/ a pitman which is a bonus, but I also got their brake lines which would also be a good idea. The next upgrade you will want to do is a knuckle to knuckle steering conversion, or better yet a hi steer.
The only problem I had w/ the install was the pitman arm was a little sloppy. The nut would bottom out on the splined portion of the output shaft before the pitman could be pressed on tight enough - it must have a slight taper to it, but it was an easy fix, just put 2 or 3 washers on there that are big enough to slip over the splines which pushes the pitman up farther. It took me about a 1/4 inch of washers to get it tight. If you have a winch and aftermarket bumper installed, you will eventually need a BB. If you dont have a winch and aftermarket bumper - call me, and we can change that! 8)
