A lot of these systems require high PSI and your average air compressor doesn't deliver it. My system requires 400 for a slow lift and 425 for a quick pop up.

Plus compressors leave a lot of moisture which will kill these things over time. Nitrogen is dry.

What is the approx. weight of a fully installed system?

always thought it would be great for a street car, but figured it would end as one of those "why do you want to do this mod" threads

great info here!

I think it would be awesome. For me there's just too much other stuff to do to my car with several thousand $, so I will likely never get this done.

No idea on price, but AST has air jacks. http://www.ast-usa.com/other_ast_products.php

Seeing that they work with GA and WC there is a good chance they have already outfitted a vette with them.

It all depends on the product itself, materials used for mounting and tubing for the plumbing.

I chose my system as it only weighs approximately 2.2 lbs per corner.

Here's a pdf on APs jacks. As you can see, you just don't grab a product off the shelf, there are many things to consider. The Porsche Cup Cars only need three jacks to lift the car --big savings!

The biggest weight is the steel mountings to the car chassis, jacks about 2 lbs each, AN lines or hard lines, inlet nozzle...my WAG 20lbs.

I have always wanted these...I think they would make my tire changing chore sooooo easy. I know there must be a legit reason but aren't these literally canisters with a plunger hooked up to lines?? why are they so expensive? Not like they need to be adjustable or tuned... If someone came up with something affordable I bet you would see all of us with them.

There's pretty cheap ones out, but the quality I am unsure of.

So about $1200 in just the jacks, and then theres all the lines you need. that with a tank of nitrogen( idk how big youll need).

Youll also be able to find mounting flanges that you weld to the frame and use the jam nuts/rings on the jacks body to fasten it.

Im just wondering how fast/quick will the nitrogen tank run out? Are we talking about a 15lb bottle? even then, how many times can you use the jacks before you run out?

Great thread

Sorry to revive such an old thread - but where did you guys mount the rear air jack?

Screamin Z

my rear jack is in the location where the frame wraps around the fuel tanks. And as far forward as possible before the long straight section by the rocker panels..

takes 220PSI to lift the 3000lbs car.

if you use a 2000psi oxygen bottle, the regulator will not give you the psi you need to lift the car. Oxygen at very high psi can be explosive.

Poor-sha

You thinking of doing this on your C7Z? I'm definitely in to see how the install goes.

schaibaa

I think I met your father at Mid-Ohio last year -- your car is nice!

Thanks for the heads up.

schaibaa

Considering it -- I was thinking of going with an electric setup along the lines of this:

Seems less complicated and although it might be a touch heavier, no need to mess with air lines, fittings, carrying air tanks, etc.

needs 20A

schaibaa

20A for 2000lbs at that speed. Most I've seen are about 5A so 20A for the entire car and for 12V DC it's really not that much. I could get away with 1000lb actuators.

Charley Hoyt

15 pounds each seems pretty also how large of a wire is required to power them? My car has pneumatic jacks and they work great.

Charley

schaibaa

i would probably go with a 10 gauge wire. Pneumatic seems great but seems harder to run the lines. The actuators I would use are around 10lbs each so I'd be looking at around 45lbs total.
