Default how many PSI in stock shocks?

well, since it was warm out today i finally finished my ghetto-rigged manual-fill air ride shocks. (pump is dead) i just need to know how many PSI to put in them.

I've done the same on my Aurora, and I fill the shocks all the way up and lower until I get 4 fingers clear between the fender well and top of the rear tires. Not very scientific, but gauging an actual PSI is not really required until you figure out whats right for you.

i just didnt want to blow them... i completely bypassed the pump, are you saying it will somehow not accept any more air once they are full, and i dont have to worry about blowing or overfilling them?
I just have no idea whether 80psi in the compressor is a good idea, etc.

I filled mine up about 75% before then weight of the car was loaded onto them, after that I adjusted to suit. Its pretty simple and you wont damage the shocks that way.

I was told on here that maximum system pressure is around 70 psi.

We put 20-25 lbs in my son'* 99.
PS - That was enough to raise the back up a little higher than normal.

Yours will have struts. The MA822s would be for a 2000+.
