Hey, i know a bit about cars, but absolutely nothign suspension/steering wise. So anyways i was under my car putting my catback on, and i noticed an air valve, like your see on a tire, under the car, below where the Z28 rear emblem is. Now this valve was a T line and had air lines going to each side, now one side was burned off by something, but the other was still connected (ovb theres no air in the lines anymore because of this) but is this air ride? or adjustable, or what exactly is this? is this good or special? or... i dont know. I will take some pics tommorow. I bought teh car from a guy for $400 with no motor or tranny,and he did do some work to the underbody of the car so im thinking maybe he put in some really good shocks in the back?

take pics of your struts and one from behind the rear end showing the whole bottom.
and the T fitting

OK. so i took some pics.

#1 is the T fitting
#2 is the broken hose (dont know why i took a pic of this)
#3 is wehre it leads to, very awkward place to take a pic, so i pointed at wehre it goes in, looks liek it attaches to the side of the shock.

those are adjustable rear shocks. they affect ride height as for performance im not too sure

good to know, ill fix the hose and play with them a bit perhaps.

Does anyone know what kinda PSI i shoudl put into em.. or. anything?

Its air shocks or had them.They where used mostly on trucks to lift the rear when towing.Check the shocks see if they have air lines on them?

They were also used in cars to gain clearance for running tall tires, for an excessively "raked" appearance, or for compensating for sagging OE springs. Other than permitting bigger tires (that make wheelspin more difficult to get, or permit wide slicks to sort of "fit") there isn't much performance reason for running them.

There are, however, structural reasons for not - shock mounts were not originally designed to carry any of the load that should be carried by the springs. Especially in older cars, or in cars that have lived in corrosive environments, there is an increased chance that cracks will develop around the chassis side shock mounts when these things are used. I think there have been cases in some cars (not necessarily F-bodies) where an air shock has torn completely loose at its upper mount.

Understand that in most cases aftermarket air shocks are nothing more than band-aids that may be hiding something. If you do keep them and feel you must experiment with them - keep the pressures low.
