Simple physics boss, that bag looks like a cylinder about 18 inches in diameter by 24 inches tall so a little over 1800 square inches of surface area. With a 5000lb car to lift one side you need 2500 lbs of force. So with 1800 square inches you only need 2500lbs/1800square inches to get 1.38 PSI. Exhaust gas pressure is more like 15-45 psi depending on the car. It will work fine.

I don’t think this “jack” is possible. You’ll need tremendous air pressure in order to lift a 5000lb SUV. Do you think a car exhaust pushes out air at that pressure? I don’t think so.

I think this air jack lifting is genious although as genious as it appears to be, it also can be very dangerous as peter said.I guess a tri-pod just to be sure wouldn't hurt.

made by idiots, for idiots. it looks dangerous and it's probably more difficult than a regular jack

These are frequently used by off-roaders, they're safe to use just like any other jack if you know what you're doing. The problem that causes them to not sell is that most Americans don't have a clue what they're doing anywhere near a vehicle and that leads to inevitable injuries.

I wonder if it would warp any of the softer panels like under the door since this jack also pushes outside the typical jack points. Great idea, but if it comes with a dent after I replace my tire, then I’m not sure if it’s worth it.
