Air Suspension Upgrade

So, as you build and increase the weight of the van, the inevitable occurs, the van sinks on its suspension.
Although we have been very weight conscious within our financial restraints, the elliptical leaf springs flattened out.
A bit of research found these after market Air Suspension kits highly recommended!



Fitment of the kit is fairly straight forward, first you have to remove the two suspension bump stops, this in my case was not the easiest thing to start with!  
One fo the fixing bolts was rusted and the captive nut welded into the chassis came loose and was rotating as I tried to undo the bump stop!
Oh well, lets cut it out then!


All in a day!  With the bump stops removed fitting the kit is a doddle!

Simply bolt on the upper plates then secure the two clamp bolts that grip onto the leaf spring seat.



The cat does insist on checking the work is carried out correctly!


All that remains is to decide the location of the air valve and air gauge, once decided, run the pipework do up the nuts and pump up the system to your desired air pressure and check for leaks.



The BIG question remaining is "What air pressure" to pump up the system to?
A bit more reading reveals so many people recommend so many different air pressures its pretty much a case of grabbing the mid range figure and see if it works for you!

We opted for 40psi for starters, to be honest it seems to work for me so its stayed at 40psi.
The air suspension kit certainly did the job, it raised the rear end of our van nearly 3 inches and in doing so, brought the leaf springs into a much more desirable elliptical shape.
The drive is improved too, it has cut down the wallowing on cornering nicely.

A good worthwhile upgrade at £250
