ALL-TOP Off-Road Exhaust Air Jack - 4000kg/8800lbs, 78cm/31inch Lift - Fit Air Compressor & Exhuast

I had an old different version on my FJ Cruiser that I sold with it. Now check it on my Subaru before on my heavier truck. I haven'a tested by the exhaust, but It works great by air pump and will help alot on dunes or snow before putting the jack or have issues with the hight underneath your car. If you don't know how it works, watch youtube videos to figure out.

Amazing

After watching several YouTube videos and reading the reviews, I'm convinced these jacks are all made by the same Chinese company. You can find them in price ranging from about $90 to about $130 for the 4 ton jack. I ordered one of the more expensive jacks because it was advertised (pictured) as being "yellow" instead of the majority color of orange; received an orange one. The warning labels on the.$90 model are identical to the $130 model. Does the jack work, absolutely yes. Although I haven't used it in an off-road necessitated situation, I did try it out at home. I tried it both with exhaust, and with air compressor. The jack will not work if you have dual exhaust, unless it is dual exhaust into a single outlet pipe with a diameter no greater than 3 inches. It also won't work properly if you have exhaust leaks anywhere in your exhaust system. Using compressed air the jack was filled to capacity using no more than 40 psi. The jack easily lifted my jeep wrangler from the side (both same side tires off the ground) and from the front (both front tires off the ground). Inflation time was about 3 minutes using both methods. The compressed air method was easier because you don't have to hold the hose on the exhaust, and with compressed air you can easily adjust the bag as needed during the initial inflation. Once deflated, the jack compactly stores in a convenient carry bag, which I stored under my rear seat. This jack is just one tool that can mean the difference between being "detained" (being able to get out by yourself), and being stuck (needing someone to pull you out).

It works for me with an air pump. The funnel shaped exhaust fitting is not large enough and it does not fit any of my vehicles exhaust tips. You have to have it sitting straight or the vehicle will tip. Seems just ok.

The bag blew up fine after a few minutes but didn't have any strength. Revved up the jeep, put it on a snow cat exhaust nothing. Don’t waste you money but more importantly don’t depend on it.
