I don't think you get them Stateside, but that's exactly the suspension that Citroen cars use for all their medium and upper ranges.
Works very well.
Does yours settle down or does it have an anti sink valve, and how long are the suspension spheres designed to last?
It would be interesting to see pics of how the rams mount into the suspension componets.
The anti-sink valve is what a hydraulic "dump" is. Basically, the hydraulic cylinders mounts to a heim joint which bolts up to where the stock shock was. I had to cut the diameter of the shock tower a little larger to fit the cylinder through. As simple as that (somewhat). The car uses the exact same principle as the Citroens, except I have four wheel motion, and control of each side of the car as well (if I have a fat passenger, I can raise his side of the car higher to compensate ).
