So I have to order new hydraulics (or the slave at least because the hose popped out of mine), and I was curious what the difference between stock and valair is besides the threaded clutch rod? I have a south bend dual disc clutch btw. 

I don't suggest the upgraded hydraulics. Most people think its great because it's adjustable and already assembled and bled. The problem is adjustable it's very possible to hyperextend the throw-out bearing past the fingers of the pressure plate and destroy a clutch quickly. The other downside is you still end up bleeding that system again because air bubbles tend to get back in from shipping and handling.

So a set of stock hydraulics from rockauto.com would work fine then? 

Matter of fact what I typically suggest is the master and slave cylinder from NAPA. The go through the bleed process.

 

 

This way you build the system from the ground up and have it bled out before you install the system and it typically works the first time without issues. I've built my system twice this way and work the first time each time. 

I lost my master cylinder about 9 or 10 years ago. I bought a replacement master from one of the big box stores. At the time I never had heard of having to replace the whole thing as a unit. I installed and spent the next 3 weeks pumping all the air out while driving it. It did work but was a pain. since then I have replaced my slave cylinder with a Rock Auto replacement. It came with a bleeder screw and made the bleed process easy. Seems the master ought to come that way also.

 That being said you can replace both completely against the rules if you have patience. Mike's way is most likely easier but I have never tried it. Other than the cylinders on mine, the tubing is all the oe stuff. My advice is you do not have to spend the money for HD hydraulics. I currently have a SB con ofe in mine. Not a dual. Ignorance is bliss sometimes.
