Ok if you have a Dana 60 and you mount the Drag link to a High steer arm on the passanger side and have the tie rod in the stock location. This is just for my example

So the high steer arm is shorter than the knuckle in terms of throw, so you only need to move it about 6" to get lock to lock, but the tie rod still needs about 8" in the stock knuckles, if you mount the Ram on the Diff and Tierod wont it fight the steering box? since the ratios are different?

Or am i missign something here. if the drag link only moves about 6 and the tierod needs to move 8 and the steering box powers the ram. the ratios are not right?

This is a single ended ram setup, will this still work?

uh...I think I understand your question...
Here's a quick rundown on how I believe a power steering box works.
As you turn your steering wheel there are some gears in the box that rotate the pitman arm. The pitman arm moves the draglink, draglink moves the knuckles, etc.
In a power box there is a shaft that is slightly flexible. As you steer the wheel that shaft flexes (in torsion) a little bit. This flexion allows hydraulic fluid to escape past some valving to assist the steering, and make the shaft not flex. so this shafts goal in life is to remain straight.
When you drill into the steering box for ram assist you're drilling into the fluid channels that assist the box in keeping that flexible shaft straight. So some of the fluid that would have gotten ported to the assist portion of the box is ported to the ram.
Since the fluid going to the ram will help keep that flexible shaft from flexing there really isn't a ratio that's needed. You will just keep filling the ram until the shaft quits being torqued. Once the shaft isn't in a torqued situation the valving will close and you wont flow fluid to either the ram or the assist part of the box.

Anyhow, I don't know if that is all clear, or even if it's all 100% accurate. But it's how I understand it. Hope it helps... :p

The box doesn't put out a set amount of fluid or move the ram the exact distance that the drag link moves. It just fills the ram with fluid with some pressure behind it. When the ram is extended enough that it is fighting to drag to go further, the fluid stops going to it (ie you have stopped turning). There is no ratio for the ram, it only assists (thus it is hydraulic assist and not full hydro)

No ratios to worry about. When you are measuring this throw is it with the steering box connected? Is the steering box hitting its stops in each direction when you reach this 6" of throw? Or are you just measuring the distance until you hit the steering stops on the axle?

If you want to get the full 8" of throw on the ram you need to make sure your pitman arm and highsteer arm are the same distance. Center of hole to center of hole on the pitman arm = center of hole to center of king pin on the highsteer arm.

If your steering box is not reaching its stops and you are using the axle stops then your ram is going to continue to push as its getting fluid from the steering box. This can cause problems in the long run as its wanting to twist the highsteer arm off.

If however your steering box is actually reach its internal stops then I think it should go into bypass and not pump fluid to the ram.

Its a little difficult to follow what is hitting the stops in your measurements.

Also the pitman arm hole to hole should be close to the same as from center of king pin to tre hole and center king pin to drag link hole. Call partsmike he helped me get mine right.
