It's also a good practice to have a secondary set of lifts under the car. This can be your hydraulic jack on the center, or a set of wheels under the existing wheels.

Something like this where the pin secures the height. The ratchet style depends on friction essentialy to stay in place and often has a large lever that could be kicked and knocked out.

This still has the risk of a pin breaking of course. That is why you don't bet your life on any of these alone. As Filippo suggested, always have a backup when using jack stands.

That large lever has a safety pin in it that will shear when there is a large force exerted on it, essentially if the car is on the jack stand it will take a crap load of force to lift the lever and the shear pin will break long before the lever is moved. Those torin pin style jack stands are also known to have issues where the load bearing surface will warp or completely break off. Plus the base is alot smaller than the traditional jack stand so those arent as stable.

Personally I use a traditional jack stand + esco's jack stand which is pin based but with an extremely large base.

All good points and even more reason not to trust any of them alone.

The R&T article explains in this case the support pawl can disengage under shifting loads - let alone the lever itself being hit.

There was a YouTube video testing it, in some cases the sheer pin did not break. But it took hundreds of pounds to lift so not likely to be kickable.

I always put my second set of winter tires or blocks under the car too, don't want my face to get crushed.

I used those Pittsburgh 3 ton for dropping my driveshaft. I was thankful Harbor Freight made it so easy to kick the pin and drop the driveshaft when it is ready to be lowered! :p


Edit: but really, I only use those cheap jack stands for holding up a wheel during suspension work... or holding up axles when removing them... etc.

When working on an suv I have a regular jack stand + hydraulic jack as a jack up with weight being distributed 60% on the jack stand and 40% on the hydraulic jack so both of them have a bit of load on it. Then I also have the wheels under the car in case.
