i am trying to find info on converting to full hydro steering. i have a cj 5 , dana 60 front, 302,c6,205. running 42" tires. will the two lines coming from my power steering pump be enough ? what else will i need other than the ram? any input would be great. thanks

You will need a steering valve matched to a cylinder, a cooler, reservoir, heavy duty pump, steering column, valve bracket and hoses.
 
depends on how much money you want to spend you can look on ebay and find orbital valves that work for what you want to do for around 200. you can use your existing pump as long as you aren't going to be using bigger then a 2 inch ram. It seems they just don't have the pressure and fluid flow to move rams bigger then that. you can go to a hydraulic shop and they can put an end on your existing power steering hose that will allow you to screw it right on to the orbital valve (depending on placement). then hook up your return line with a filter in it and run your 2 lines to the ram. A cooler is a good idea too but you can just run a tranny cooler from advance if you want.
 
pirate had a good writeup on full hydro couple years ago. think its still on the tech page. if your using a gm saginaw style pump, it puts out 1500- 1800 psi at 5-7 gpm. X2 on olebrokeys comment on you dont need bigger than a 2 inch ram. just remember the bigger the ram, the more power itl have, but the slower it will move. i think some guys will put a underdrive pulley on the pump to spin it faster for more pressure(power) and then drill out the oriface for more flow(speed). mixed results on that, though. hope that helps also. budget building takes a bit of math for the flow rates to be optimal. on the orbital, your looking for a load reactive, open center type. see ya on the trail
