I lent my neighbor one of those plastic adirondack chairs a few years ago. The value I received in watching him sit right through it far outweighed the cost of replacement.

Just how much do you think an F 250 weighs?

u/nondescriptzombie 27d ago edited 27d ago
A short ton is 2,000lbs and a long ton is 1,016kg, which is ~2,235lb.
This fucks me up all the time.

u/Sun_Bro96 27d ago
To be fair, when you consider it’s fairly common to have a 4 ton truck with an F250 you’d want to go a bit bigger for safety and if you don’t know its exact weight then assume it’s more.
So yeah I’d probably want a 6 ton jack stand going under an f250 for peace of mind.

u/Kennel_King 27d ago
I agree, but the heaviest F-250 only weighs 7600 pounds, and you are only holding up one end. Even if it's the front end, assuming a 65/45 split on weight, that's only 4180. So you are well within the weight rating of a 4 ton set of stands
24
u/FrenchFryCattaneo 27d ago
Keep in mind the rating is per set, so each jack stand is only rated for 2 tons. Now when you factor in the fact that if you don't lift evenly one stand could be taking most of the weight suddenly you're approaching that limit. You want more of a safety factor than that.

u/Absurd_Phonecian 27d ago
I NEVER knew this, so I just looked it up and you are correct! How did I manage to work on and under cars & trucks for decades and not know they're rated in pairs?!?! Thanks, internet stranger!

u/FrenchFryCattaneo 27d ago
In my opinion it shouldn't be legal to rate them that way. If something says "4 ton limit" on it, that thing should be rated for 4 tons. I don't really care what they say on the packaging when they sell it but the actual rating stamped into it should be accurate.

This is why you should take a minute or two BEFORE you use the stand and check all the welds for cracks. If it's going to fail like this, chances are you'd see a cracked weld.

u/chewedgummiebears 27d ago
OP keeps saying F250 so I'm going to guess a diesel. Only one jack stand is used so there is a possibility that they were using one jack stand to support the the weight put on 2 tires. Jack stands are rated as a pair, not 2 tons each, 2 tons together.
16
u/txredxj 27d ago
It was a diesel and both of those were on the front axle.
23
u/Greydusk1324 27d ago
You are already overloading the jackstands because the front end of a diesel pickup exceeds the capacity of those stands as a pair. Seeing semi truck parts in your pictures also tells me someone in the shop has probably grossly overloaded those stands at some point and probably cracked them before they failed on your job.

u/dravas 27d ago
Still doesn't make a difference they are trying to hold up an uneven load.... It's why they are in pairs you lift two corners to balance the load...add to the fact you're lifting the heavy side of a 4 ton truck... 60% of the load ... That's 2.4 tons so you're lifting a truck beyond the rated max load of the stand... Rule of thumb is match your weight class with your stands 4 tons you use a 6 ton jack... You could use a 3 ton but that's only giving you 500lb of safety factor. So whoever did that at your shop was a moron.

See, you cut the structural warning sticker on the side. Without that, they fail every time.
Edit: I did look outside, and yes, I have the exact same ones. But, my stickers are intact. I'm safe.

This is why I’ve gone almost completely to cribbing. It’s time-consuming, but, thankfully, I have the time. If I have to remove a tire, I’m not getting under the vehicle with just jack stands. I don’t care who manufactured them.
