So the French took an air shock, attached a hand grenade to it, and made it better?
French technology never ceases to amaze me.

Yes, The system is based on a sort of air shocks but you have the benefit that you can add or drain oil depending on the load condition so you always have max comfort for each load case and the truck is level .

Update!
Installation of system done.
First i put the hydraulic pump blow the rear battery tray (do not mind the rust gap)
Then i routed the hoses thru the front
Used a old expansion chamber from a Mitsubishi van as a reservoir (the citroen one did not fit
and put in some levers for Control
I have tested the system in its highest mode for 2 weeks and it do not leak anything

Wow, very cool!
Nice! Now where can I find such a system on this side of the pond?

Its far between my updates but the project rolls on. Now i have this system on both axles and i have filled the spheres with the correct amount of nitrogen and the right sized damper holes considering the weight of the car. It works fine but i have set the dampening holes size for good handeling and that makes the ride almost as stiff as before. I am now in the process of implementing the "hydractive" system from citroen. It means that i can choose on the fly "sport" or "comfort" mode. In comfort mode 3 spheres will be connected for each axle, give a softer "spring" and the oil will be allowed to run thru bigger sized dampening holes to give softer dampening. The oil will also be able to flow between right and left hydraulic cylinder on the same axle. In sport mode there will be 2 spheres for each axle and the flow between cylinders is blocked to prevent swaying.

Everything is custom made but a citroen C5 makes a good donor!
This is so neat!! Keep it up!!

Thanks for the comments and here are some more pictures
I have ordered two pressure gauges for the front and rear circuit, i intend to install them where the radio was originally mounted
At the same time i ordered inline test points so i can tap into the circuits
I managed to squeeze in the front cylinders but it was tight!
I could use the "extra" upper mounts but had to manufacture new lower mounts. I will shave of some material later.
Here is the Hydractive valve i collected from another scraped C5. It need 2.8V (of course, its French...) so i have bought an adapter from 12V to 3V. I have hard soldered a 1/8 adapter to the pressure line, the cut one is to tank. I bought adapters from M16x1,5 to standard 1/4 and from there to 3/8 (the size to the cylinders)

I have always wanted to do that.
I had a few Citroen cars growing up in the middle East I even kept a gs that had a bad engine to get the parts, but then I came to the states and my dad scrapped everything.
Glad to see someone doing this

Today i installed the valve and it works perfect!
Since i'm going to a big "raggar" party this midsummer i also installed a awning.
There is no better way to spend a Swedish midsummer then in the company of a bunch of hillbillys drinking insane amounts of beer, reving up old american cars and incinerate pig meat. The fact that the party take place in absolute nowhere is a big bonus i supose

After a load of problems i have now installed gauges so i can see from inside the car what pressure i have i the front and rear system. Left gauge is front and right gauge is rear. The switches is for raise/lowering front and rear

I will update soon, Winter season has just arrived in Sweden so i will loot another Citroen C5 this week for a valve to the front.
