My question is how quickly does it deflate when you want to lower the car back down?

PSSSS......BAM....

 

I wonder if it has a one-way valve to keep the air in. Otherwise you would have to keep the car on to keep it filled.


That thing looks hella dangerous, BUT Id try it on a car that wasent mine.

I bet its fun deflating the big bubble of carbon-monoxide at the end.

 

I'd definitely consider using it for just changing a tire. It's not like the crappy stock scissor jack is any safer. They're both not meant for getting underneath it.

 

Particularly well suited to use in sand, mud and snow, and with a lifting capacity of 8800lb, the exhaust operated X-Jack is an invaluable recovery tool, providing up to 31" of vehicle lift.

thats pretty sweet! In my opinion this is safer than the scissors jack that comes with the car. Have you guys used it? You car can fall off it VERY easily. Especially when being used on the side of the road where it's typically used. This is pretty much just a big airbag and those things are used on suspension all the time.

 

If you know where your putting the scissor jack, its very stable. I definitely wouldnt trust this air bag holding the car up, glass or nail could potentially rupture the bag, sure it may have reinforced rubber, but I wouldnt want to risk it.

Remember, this thing costs $130 guys.

Imagine what kind of compact jack you could find for 130 bucks...

 

^^^ true, they cost quite a bit, but the jacks actually work quite well. as for the worries about glass, nails, etc.... they all have a hard plastic bottom which you can't see in the pic. true, the scissor jack works great on asphalt, but will acutllay sink if you are on soft soil like a nice muddy dirt road. just kinda depends on where you live if you would use this or not.
