4-Ton Exhaust Air Jack - Portable Inflatable Car Lifting Bag for SUV, Truck & Off-Road Vehicle Recovery Emergency Tire Change Kit for Uneven Terrain

Fast deliveryworks great and easy to use for my Silverado but better use compressor rather than car exhaust.

I bought this as a lighter-weight, more packable, alternative to a standard farm-jack. I am pleased with the way it fulfills that role.

Very impressive, i use it where not recommended but going strong

The Jeep has only one round muffler would not work on a two outlet muffler.

Got it for the side by side, light weight, durable as hell

It will lift for sure, but for how heavy I won't know, I got it to lift something that is only few hundred pounds and it take timesI used compressor air to inflate it, it takes time, really slow, maybe reving exhaust will be faster, but not sure its a good idea to connect to a car when its jammed?If you like to use it for your road emergency, remember to open it and pump it out once at home first, otherwise you will have a very hard time try to locate the top and bottom side when unfolding it since its packed sideway and all stick togetherThe inflatable tube still fold up with some thickness, so if your car is jammed with not much clearance, you won't be able to slide it underneath it since it is soft unlike a tradition jackI lifted my stuff only few inches high and I won't say it is very stable, I can feel it wobble when I loosen some nuts that isn't require much force; I will not 100% trust it if you need to loosen up the wheel nuts or something that require strong force or wiggle; since my didn't inflated to the max height, the tube was kind of created a bubble around the frame but still wobble and I was on solid ground, so if you need to raise to the max height, I don't think it will be very stableAlso you want to avoid sharp edges, a car weight few tons even the corner of the frame might puncher itBottom line is, it will do its job, but if you need heavy duty or in more extreme environment like off road, get a proper Hi Lift or other jack; if you just need it for changing your tires on normal road as a backup... use your car's own jack or those scissor one, this one doesn't really pack that smallPS, the including "gloves" are those super cheap one no one will want to use even handling light duty in China, don't rely on that pair

Used it right out of the box. It is a well-designed, functioning piece. It is quick also.

Tried this on my 2020 Revel Class B van (2019 MB Sprinter chassis). Would not lift either the front or rear wheels. Tried under factory jacking points, and under the rear differential (with a flat diff skid plate). Tried as test on flat asphalt surface. No go. Couldn’t get wheels and tires even close to off the ground. It says it will lift 8500 lbs, so should lift the front or rear corners of this under 10,000 lb van with no problem. But, it doesn’t. Disappointed with sub-par advertised performance and cannot recommend.
