I like the RC kit. It was pretty easy to install, its just time consuming. Didnt have any major problems. You definatly need a buddy helping you though. I didnt have a problem with that, I just bought some beer, and I had no problem with volunteers. It took about a day and a half, and all you need is a socket set with up to a 7/8 inch socket. I spared myself the headache of doing the pittman arm installation, and took it to the shop ($25). You need a impact wrench for that. I have had it on for about a month and a half, and no problems. I havent had much of a chance to get it off road, but what I have done, I am very impressed so far.
