You cannot compare old to new springs outta the car and on the ground. Get em in the car then see how it sits.
a stiffer spring will not compress as much as a softer spring. so even though the newer spring has less arch to it, if its a stiffer spring the ride height will not be as low as if its the same stiffness as the old spring.
I'm gonna install one and see. I called S-n-T to ask if I can exchange them if I'm unhappy, even after they are installed. They said yes, so Ill get one on when I can, and see how it looks
the two different springs will fight each other. leaf springs do not like to twist. when you tighten the u-bolts down on the differential it will link the springs and they will fight with each other to get rid of the twist. i would expect the results to have the ride height end up being between where the springs would sit when matched.
