You would be better served by replacing them with some high quality shocks. If you need additional ride hieght. There are better ways to get it. However, if you want to inflate them, try using 5 lbs increments until you get the desired result.

That stance looks good. As along time mechanic who lived in the north I've seen more than one car with the shocks pushed through the floor. Yes they were rusted cars but it does happen. It's not a myth it's the truth. Using salt to clear icy roads causes a lot of rusted weak floor pans. look at all the guys having to replace trunks and floor pans. Shocks were not designed to support the weight of a car.

yeah sounds good i had the feeling i might need to freshen up the susp. on my ride, for the mean time how does this look as far as a typical belv stance goes, maybe im just too into a beefed up looking rear,

Nice car
The ride height in that picture is hard to judge since the car is on an incline but it doesn,t look to high to me at all , i,d break out the compressor i,ve seen my share of damaged shock mounts on SOLID cars from air shock abuse,plus they ride like a horse wagon but with low p.s.i. you sould be fine for a while .

i was under the impression that air shocks work very well if they are not overpressurized... so 15-20 psi (not 20-25 psi) is a normal amount? didn't lincolns and those mark viii factory hot rods have air shock suspensions?

I believe they are air bags not air shocks. Much different deal. Most of those old air shocks didn't even notice 20 psi. Over pressure on air shocks is 90+ psi.

The Lincoln MK 8s did use an air shock type suspension on the front, air bags on the back and it worked pretty good. I have run air shocks on my cars for years and have had zero problems with them. If they beat out the mounts, you had bigger problems anyway. What is worse is topping out the shocks on a high performance car but no one on here ever claims that happened to them. I have run SS springs with drag shocks all around and then swapped them all back to stock type gas on front and the airshocks (with extensions on back to stop topping out on launch) My mid 11 second street car saw NO difference in 60 ft or anything else and I kept very good records while running the bracket program at Houston for years, and was getting about 6" of air on launch. Load up several friends and put their gear in the trunk, add 25# of air and take off on a trip without looking like a low rider. Air shocks get a bad rap from many of the experts here, but most have little or no experience with them. When they became popular in the late 60's, early 70's there were many articles in the mags about using them at the track. By running seperate air lines, you could preload your right rear tire for a better launch. They are not a panacea for a worn out rusted out car, but used properly, they are a usefull addition for many street/strip cars.

My Satellite already had them installed by one of the previous owners when I got it, but I keep mine at 50psi. I would never actually spend money and buy them myself.

You do know that the Lincoln was designed to run air-struts and not just tossed onto a now 30 year old car. Right? Mercedes Benz ran them for awhile as well. I dont think the concern is for 60' in a drag car, but more of the increased load on the upper shock mounts in the rear of the car. Pictures have been posted by 'non-experts' running air-shocks on some not-so-new mopars, they show clearly going through the back of the trunk. Cars were just not plain designed to carry the load there (unlike the Lincoln you mentioned), it was meant for the springs.
While thats great your drag car doesn't mind the air shocks. The concern of the thread is most street Mopars get beat-up in inadequate stregnth places. I've run them on my car, there is no way that severe of a ride when 'jacked up' was anything but bad for my car. They were on a very breif time, and swapped for the proper leaf springs to be used on the street. Your drag car isn't hitting speed bumps, rail road tracks, dips, pot holes, driveways, etc, etc.

Sorry, you misunderstood. My streetcar is bracket raced. When I say street car, I mean driven in the 98 and 99 Hot Rod Power tour, driven from Houston to the Woodward Dream Cruise and back and driven for the last 20 years with airshocks on it. They serve the purpose they were designed for and were factory optional on some cars, Ford station wagons being one of them. Just because you have had bad experiences with them, or known people who misused them, does not mean they are not a viable shock for a street car.
