We have all walked the line of safety but when you increase the height the more risky it becomes. Only advise I can give is when you raise the floor jack it moves another reason for the wheels when placed on wood with weight of the Jeep the wheels might not move this might cause the jack plate to slip off what ever you are under or the jack to lift in the back both outcomes are not pretty I seen this happen so if that is the route you are taken be extra careful of the surface the jack is on good luck

You can actually have too much of a good thing where you're having to work at arm's length while laying under the Jeep, depending on what the job is.

That's just crazy to look at. I don't think I would go under it. And with the ladders to get in?! No thanks, I'm good. Mark sometimes you guys really push the envelope...lol

Everywhere online shows the stands being by frame side of the control arm brakets.

I think I'm set on the 30" models, they are 12 ton and should be more than enough for anything i'll need in the future. if I need some additional height for my jack or stands I'll make some cribbing out of 2x4s or 4x4s. Didn't even know about this until I was googling late last night.
Be warned the the 12 tons are to tall, believe me or not but the 6 tons I have with a 4" lift and 37s I only go maybe half way up at the most and the 12 tons are way taller unless you have 6"lift and 40s then yeah you might need the 12 tons

And also of you get 12tons you can only use them on the frame so whenever you need a stand for anything else they won't work as where 6 works on the frame and the axles if needed

The pictured JK is on a lift and the four red stands are used as safety stands to stabilize it.

I agree. It's best to use two floor jacks and evenly lift the front or rear evenly vs. one corner at a time. My six ton jack stands will tilt if I lift the opposite side too high. I have two large jacks and four six ton stands and can get the JK plenty high enough off the ground for any task.

The Jeep is still on the vehicle lift. It is a 6000 pound, single pole lift. Its arms are under the frame rails. The stands are just for additional support, and can be placed wherever needed--such as under axles when loosening control arms, etc.

It is still on the vehicle lift. Look carefully.

Ah. Gotcha. I was focused on the stands. I can see why that particular lift needs supports.

I thought the legs on the floor were the lift. I was wondering why they were dropped but thought maybe they were in the way of what you were working on. Good to know that you wouldn't support a JK this way.
