Please tell us what the ride height specs. are.

Front air bags: done!
I'm happy with the outcome, achieving the targeted lift (3 inches) at only 70 psi. I can't really feel a difference in comfort, maybe a little firmer in the large dips, which is good. I used a height control valve and connected the airline into the auxiliary air system, works perfectly.

Here is a list of the parts I used:
D2500 air bags (two on each side),
One inch heavy duty air spring spacers, between the bottom of the bag and the leaf springs,
Two "T" pieces of steel (6 inches wide, 24 inches long) to secure the top of the springs under the frame rails,
8x cams valve springs (I'll explain later),
Haldex height control valve.
1/4 air hose and fittings

Why the valve springs?
I secured the spacers on the leaf springs with a U-bolt. But on my bus, there is only two leaf springs (on each side), and there is a small space between them. When the suspension goes up and down, this space changes. So, I was worried securing the spacers with a U-bolt on these leaf spring would not be mechanically correct. That's why I used the cam springs between the plate of the U-bolts and the nuts.

FANTASTIC !! This should be a sticky thread somewhere for any that look to level their bus. Great job on acknowledging the spring action physics. If you were in my area, I would pay you to work on my equipment.



Sometime I would like to see pictures of your control valve location and mounting. 70 psi to achieve the result you were looking for? Huge thumbs up.



Thank you for taking the time to write up a follow up and post it here sharing your results.
