^^^ what he said. I had to change the Currie one with the PSC clamp. Also run the EVO drag link flip that I had burned on before getting the PSC setup. I had to modify and strengthen the EVO kit, as it would flex without any modification done to it once the PSC ram kit was installed.
I have a hi-lift jack and I use it all the time to pull out fence posts and shrubs. You will just need chains and a shovel and it works great. As far as what I use for the Jeep I keep a bottle jack and a 4x4 block in the back.
