We were checking our shocks today and we found out we have air shocks on our 66 Coronet 440. There was no air in them at all so we put 40 psi in them. Does anyone know how much should be in the air shocks for normal driving and no load?

 

from what i have read, people say 40 is good for under a small load, and not to go under 20. so if i were you i would go around 30 PSI.

this is just a suggestion, don't hold me to anything.

 

If you are inflating an air shock, what you are doing is turning the upper shock mount into a load-bearing portion of the suspension. Something it was never designed to do. Yes, folks have gotten away with it for years, but that dont mean its right. Safe bet would be inflating till just before it starts raising the car, and taking the weight off of the springs. JMHO

 

Instructions with the Gabriels on the GTX say to never allow the pressure to go beneath 15 lbs for proper operation.

 

You may need new ones if they had no air in them at all.

Scotty - If the car came with air shocks installed from the factory, then most likely the car was built for them.

 

i doubt it came from the factory
just put air into them until the car levels out, or picks up at all

 

I doubt it was factory either. But if you MUST use them, use them as a tuning tool. Separate the lines so that you can individually control them. On a single line, around a corner, when one compresses, the air goes to the other, causing poor handling. One could then adjust the individual air pressure to make sure the rear axle plants the tires evenly. [matching black marks!] But I am still against using them in any way to support/raise a body without the shock-towers being reinforced or designed for them.
