you will be watching for a long time

my book says CMU's compressive strength = 6000psi. think about it, how heavy is your house and what do 100% of builders use?

Not sure what length they are and not home for the next year and a half to measure them. I am gonna let the springs settle and see where I am before cutting off the excess shackle, I may use the next hole down in them before cutting the rest off.

This might be true when used in their intended application, but as a jack stand it's down right dangerous.

It's the same concept as standing on an empty pop can.....Holds your weight fine until something causes it to buckle and crush.

On the subject of cinder blocks, why use them? Seriously. Yes they hold a hous up but it is a whole foundation of them up against dirt. Under a truck I've had to many hammers and wrenchs slip that could have hit a cinder block and caused it to chip and crumble. Granted with a crappy jackstand it could have knocked it out from under the truck, but that is why I try to always have more than one jackstand under each side, or at least a log, rim or something. No one is trying to insult your intelligence, we are just looking out for your safety.

and yes..i made a hybrid pack with B2 leaf and F150 leafs. after entering all their specs in a spring rate calculator....ive only got a 187 lbs-in. spring rate yet a higher spring load which is why it flexes way more but also lifted me and supports way better.....not sure exactly how all that works but whatever works lol

So let me get this right, You used the b2 main leaf, and the f150 lower 3? What year f150? and what model? F150 springs can range from a 2.5" lift all the way to a 5.5" lift on a rbv due to the million combinations of ext cab, reg cab, long bed, short bed, high boy, etc....
