I don't have that exact one.... But I will give you my 2 cents on RC. Many have had luck, many hate it. It lives up to its name, it is rough country. I have the 4.5" system from about 6 years ago, I started changing all control arms after 3-4 yrs. mine was the threaded in the center of the arm style and the threads stripped out and the arms would move similar to a shock.
I think for that price you are much better off spending your money on ironrock offroad. They have a much more complete kit and its better quality. No matter what kit your choose, at that height your must have adjustable track bars front and rear. If they aren't in the kit, figure that into your pricing budget. The only RC parts left on my zj are the springs, and they are stiff, but I can live with them.
That link is the kit that, IMO, is 100x better and more complete, and higher quality. Again, many have had luck, some not so much. RC is a good for the $500 range lifts, but when you go any more than that range I feel your money is better spent elsewhere.
There are tons of lift threads on here....and it's more than just putting longer taller parts on and jump in and drive. I don't know your skill level, but you need to know about suspension geometry and how to correct it once you lift.
And it's a slippery slope, next you're gonna want bigger tires to fill up the space from the lift, which will need gears to get it back to feeling like normal. Then you're gonna try bigger obstacles and deeper holes, which needs more power. So you mod the motor, which then you're gonna have to upgrade the transmission to handle your new power...and on and on and on. Just remember its a lifestyle and you'll be fine. LoL
