When looking at lifts keep a couple items in mind. If a failure occurs it will happent when raising or lowering. No way will any fail when sitting on the blocks. An 8000 lb car over 4 legs is 2000 lb per leg, what a joke when it comes to any type of steel. The only failures I have ever seen is when a pulley comes off, this allows the leg to kick out and then we have a problem. Most are held in place with a ring which is held in place with a set screw, as long as they stay tight no problem, oh if you are not mechanically inclinde enough to understand the working of the lift and inturn inspect you should not have one. I have a POS cheap chinese one, it has worked flawless and regularly put our Tahoe on it. I did calculation on ever fasterner assuming grade 1A, the weakest that nobody would imitate and every single one has a factor of safety of at least 8!!!
