Bestauto 4 Ton Exhaust Air Jack 8800LBS Capacity Inflatable Air Jack Off-Road Exhaust Air Jack Lifting with Bag for Vehicle Car Truck

I have a Ram cummins truck with a slide in camper in the bed. the tiny factory jack will not cut it if I need to change a rear tire. I tried this. it lifted my truck and camper easily. I have a 5" exhaust so I couldn't use the exhaust to fill the bag but I have an engine driven onboard air compressor and I inflated the bag with that. a word of caution, be sure to check your lifting point for sharp frame edges and use the protective matt they provide on top of the bag. I have punctured one bag but quickly got a replacement.

Does not work if you even have so much as a pin hole Leak in your exhaust system.

I can remember when I first saw one of these, but I've wanted one ever since. I thought it would be great for helping to lift a car up in soft sand or silt to get unstuck. I tried using it on a vehicle weighing less than 3000 pounds. with 3 people involved, 1 to rev the engine, 1 to hold the air bag in place & 1 to hold the hose on the exhaust. The person hold or should I say attempting to hold the airbag square was failing miserably the person trying to hold the hose on the exhaust was burning their hands even with gloves on. Being stubborn we kept trying & finally managed to create an exhaust leak!However unwilling to give up easily we tried again with possibly worse results, my biggest regret is that this wasn't filmed as now that it's been a couple months I'm certain it would be hilarious watching us try to make this work.

I have only tried this in the driveway to make sure I knew how it works, it is difficult at best to get a seal on the keeps exhaust pipe but it is cut at an angle, it only lifts to 30 inches as well which would be fine for unmodified vehicles but it don't even touch the bottom of my Jeep and I only have 35's on it, it does work with the air compressor though and it seems well made, I'll carry it until I can find a larger one, 4 stars just due to the difficulty using the exhaust.

The media could not be loaded. Very impressed must have for your utv or sxs. Super light weight im guessing under 5 lbs probably like 3 lbs but can lift alot. I'm not sold on the exhaust fill with the side by side but I use a small stop & go 12v. Compressor and have had great results. Light weight packs away nicely and has over 30 inches if lift what more could you ask for.

Wanted to use this product for my utv but nobody said anything about not having enough back pressure on a utv exhaust to expand bag. Found out to late to return and does not work on my tall truck.Also not red as picture looks it orange👎🏼

Total failure. Tried to use it a few months ago when my truck tires were slashed. After almost killing myself with carbon monoxide (you have to press hard on the "funnels" to completely seal against the tailpipe, which is impossible to do once pressure builds) I just called it quits and used the factory supplied jack. Which works pretty well actually.The major problem with this device is twofold. One, it requires very high pressures to provide enough enough lift for the tire to clear the ground. So high in fact that pressing the funnel to the tailpipe is pretty much impossible. The second issue is the tube that connects the funnel to the bag. It's collapsible, and made of a stiff material as a straight tube. Therefore. any bends between the bag and where the tailpipe is will choke (pun intended) the exhaust flow.This might work ok with an atv maybe, but not a full size truck. And btw, bought the 4 ton version. My truck only weighs 5400lb loaded. Less than that at the jack locations.

I lifts very well.
