Quote: I called Heidts Hot Rods and they said the power steering valve was for a GM pump lowering pressure to a Ford rack in pinion rack. They didn't seem keen to use it on any other application.
I'd consider that a liability issue or a fitment issue more than anything else. All their device does is dump excess pressure back into the return line. On a Mopar where you are trying to reduce the pressure only slightly, you'd simply screw the adjustment almost all the way in. My guess is that since it might not be a simple bolt on, i.e. you might have to make your own lines with differing ends, they don't want to deal with the support issues.
