Exhaust Jack Takes the Work Out of Changing a Tire
Have you even been on the side of the road with a flat tire and had to cringe at the though of pulling out the old scissor jack, crawling on the ground to get it in the right spot and spending the next 10 minutes lifting the car far enough to do the job? Next time this happens, the Exhaust Jack could be your answer.
As if we needed any more proof that the human race is doomed to laziness. Anyway, the Exhaust Jack does exactly what you are thinking. All you have to do is take it out the bag, unfold the oversized cushion, place it under the frame of the car and insert the hose into your tailpipe. According to the designer it is able to lift a 3 ton vehicle up to 18 inches and hold it there for 45 minutes, which should accommodate even the most unsavy driver.
It is also 100% safe for your vehicle. The pressure build up will usually never exceed 0.7 atmospheres, which is roughly 10.3 PSI. It can also be used to free stuck vehicles if you are off roading and I'm sure at least one person has found it useful in a non-automotive purpose. (Buy here )
