For the rear air shocks, whats the max PSI? Thanks

I vaguely recall the last time I had a set the filler valve had a mounting ring that listed the max pressure. I recall that filling to the max jacked the rear all the way up in the air! I would check with the manufacturer of your shocks.

The shocks can stand more pressure than the mounts can handle, they can go as high as 100 psi !!!


I'm thinking GM says 50-60 psi tops because the mounts are not designed to support much weight. Air bags are better for loaded conditions, no mounting issues with them since they fit inside the springs.

thanks guys, if it matters the shocks are Monroe PC10CA1

Are you going for a certain look, or are you hauling? Either way check the condition of your rear suspension bushings. I found mine are pretty much destroyed, which would explain why it was binding when I aired up the rear. I never ran more than 35 PSI while cruising. I did however run 95 PSI with a ton of pavers in the bed.

Well the ass end of my car is sitting super low so I was looking for a way to jack it up. Because here's something really really, I mean really odd. My car has a corvette rear end in it. It has an independant rear axle. So, it doesnt have any springs back there, just the shocks.

GASP!!!!

Now that opens up a whole new outlook on things!!!

Are you sure there is no spring/springs ??? Corvettes have a transverse spring(runs from side to side not front to rear), cold be a single or multiple leaf set up with standard shocks. Look again and see if it has one, I'm bettin it does, if so the shock mounts could be strong enough to stand 90-100 psi in the shocks.

I WOULD NOT RELY ON AIR SHOCKS ONLY !!! BUT, If you have air suspension that would be excellent, can you describe what the "shock" looks like?

Try to post a picture, I'd like to see what you have.

Well, what I meant by no springs is no springs like a solid axle with two coils on each side. yeah, I got some pictures of when I first got the car, don't know if it shows the the shocks too well. I can take pics of those tomorrow. It has a mulit-leaf spring streching from wheel to wheel. The guy said that he thinks the rear was out of an 80 vette.

Let me resize those pictures, right now they are 8 megapixles and I think thats a bit to large to post, so I'll resize them and put them up.

Holy moly.........

That is a Corvette rear alright. I don't have any experience with that one.. Looks crazy though! I am sure there is an aftermarket company that sells stiffer rear springs BUT........ I don't think you would wan't to change the geometry of the axles. They look like there a bit high already. Is there any way to raise the chassis up in the rear for more clearance?

COOL !!!

Yep, probably late 70s early 80s Vette rear !

In that case just make sure the shock mounts are structurally sound and pump the shocks on up. I think some aftermarket air shocks are good up to 150psi, I think you could go 100psi with any of them.

The Vette spring appears to be arched about the same as it would normally so the elky doesn't seem to have it overloaded. If theres a spring shop in you area you could have it re-arched to better suit your needs though. Lots of aftermarket vendors for different springs also. Some companies make fiberglass replacements like the later vettes have and they can make them any spring rate you need.

Here's a link to one that may help

You think thats alright to have in there? I am kind of on edge about it and kind of want to switch back to a 12-bolt.

It is not the best set up if you plan on doing any drag racing but otherwise it should be fine. If you're not happy with the ride hight you could possibly have a competant shop modify it as needed to set it where you want. It took a lot of fabrication to install it and may not be easy to return to a solid type axle, it just depends on how it was done. I suspect the stock upper spring and shock mounts are long gone and some type of crossmember in thier place to mount the vette housing.

A lot of people would love to have that set up and from what I can see in the pictures it seems to be done properly, if the crossmember/housing mount is adequate. It should also have some form of 4-link control arms and I can't see that in the pictures. Street rodders have been doing that conversion for years and some muscle cars have been set up that way too so it's not common but still a desirable mod for those who want IRS!!!
