I have a pro comp leveling kit. The Ready Lift is just a 3" part the goes onto of your coilover spring. It is not too hard to do if you know what to do. My truck already had a 3" block on the back that is why the regular leveling kit was not good enough. My truck still was'nt level.

I am quite sure that comes off with the new lift. So you can have it as well. And of course my truck is a 4X4! LOL.

You may want a professional to do it because of the spring but if I remember correctly, my mechanic did'nt have to touch the spring??? I will ask... He is really good, way fair cost, and fast. Probably could put it on your truck super quick for you while you were here. Just a thought.
