You really can't see the leverage exerted on the length of spring
by a longer shackle? You will need to plug in the value at:
http://www.trebuchet.com/hardware/load.html We know that for the shackle
for the sake of argument the weight each shackle supports is about one
eighth of the Jeep, and that the stock shackle is nearly straight down,
in the short stock position, like a stilt, where nearly no energy is
trying to straighten the spring out, but you put the longer shackle on
it, it then tilts forward, that distance is the figure you may plug into
your model, a force that wasn't there before, you may take a breaker bar
and try to force it back underneath, but you'll soon learn that new
force is now too great. I suggest taking one of your classes.

If you are accomplishing all of that lift with those shackles, they are too
long. Those are much longer than mine, and they are going to cause you
problems.
