Well it does say "Super" on it...does that help? Sorry, I haven't had the luxury of upgrading my power steering pump yet, but I'll definately put it on that Christmas List that was going around here today:-) Good luck to ya!

You can upgrade the pressure of your stock pump: <a target="_blank" href=http://westtexasoffroad.homestead.com/powersteering.html>http://westtexasoffroad.homestead.com/powersteering.html</a>

You can also rebuild the stock chevy pumps without much trouble at all. Then do the mods that Steve showed you and you are done for just the price of a rebuild kit at NAPA.
See Ya,

I replaced mine with the ARG pump and steering box and it made a huge difference in the effort to turn the wheel and shortened the number of turns required. The problem I ran into is that I decided to do much more serious work including a D60 front axle. Now when it all goes back together I will need to go back to a 2 wheel drive steering box for cross over steering. It was a major waste of money doing the ARG thing in my case.

That's what I was going to say: The AGR pump is obviously just a modified Saginaw pump. They are probably not doing anything except using a new fitting and valve and covering it with paint. This is stuff that you could do without opening the pump or even taking it off the truck!
However, doing this will increase the assist on and off road. These trucks are valved pretty light already. That is part of what some people perceive as bumpsteer, too. You hit a bump and the wheel turns so easily that you inadvertantly turn the steering wheel. Modifying your pump like this will make this problem worse.
The AGR pump and box are meant to go as a pair. The box has a different gear ratio, like what you would find in a car, with fewer turns lock-to-lock. The added oil flow helps to compensate this. Plus, this gear must be valved pretty light. If you knew what you were doing and how to set up the gear, you could probably get the parts from a couple of old gears and make one of these.
For a rock ram setup, modifying your own pump would definately be a must, because the added volume of the ram would require a lot more oil flow. But I would use my existing gear and just attach some fittings to it in front of and behind the piston.
