Most jack stands will have a seam running down the middle of the stand where the two parts were welded together. Things to Look for when Buying Jack Stands: For that car, any jack stands would work, but when you’re talking about getting under a Ford F-350 Dually Diesel truck you need to be way more careful what jack stands you are using. When we used to race stripped out Mazda’s at Laguna Seca (chump car) we would literally just lift the back end of the car onto jack stands with two or three guys. Or you can spend a little bit more money and get a much higher-quality jack stand that you will confident getting under.Īs a general rule of thumb, the heavier your car or truck is the more dangerous it is to be under. You can either buy the cheapest of cheap jack stands and figure they ought to work okay. You are trusting your life to them, and therefore you have a couple options. Jack stands literally keep your car or truck from falling on you while you are under it. That is why I cannot stress enough that when buying jack stands you should always buy a much bigger jack stand than you need. Not every jack stand is individually tested by any quality assurance board that is looking out for you, the person underneath the car. Spend a bit more! Just because a jack stand has a high weight rating does not mean it is a quality jack stand. They are the only thing keeping the car from crashing down on you while underneath it. Jack Stands Quality & Weight Ratings: Source.Īvoid buying the cheapest jack stands. Typically the way it works is companies send in a pair of jack stands for testing, and also test them in house, but once they are certified there doesn’t seem to be any regular interval that they are checked. That is why I stress buying jack stands for a quality brand is so important, they will have their own quality assurance procedures. However, each individual jack stand is NOT tested before it is sold. How do they measure whether or not a jack stand fails the ASME test? The jack stand must not have a permanent reduction in overall height, measured after the removal of the load, at the point of load contact shall not exceed 0.125 in. As long as the jack stand doesn’t fail at 9-tons on a single jack, then the pair passes as a 6-ton jack stand with ASME certification. T herefore, a 6-ton rated jack stand pair each individual jack stand would be tested at 9-tons. He told me that to meet the standards set up by ASME each jack stand must be tested to 150% of the rated capacity of the pair to pass. Make sure you are buying ASME certified jack stands I just got off the phone with a representative from US Jacks.
