55.2-59 New rear leaf springs, do these look normal?

[tattooedblue]

I am helping a buddy with an 8.8 swap into his 55 series 2 panel truck.

He bought brand new springs for it, and after putting the full weight on the axle, they go from arched to almost flat.

Not completely, but a lot flatter than I was expecting. I did not see how it sat with the springs he took out, and was just wondering if these look right.
(other than u bolts still need to be trimmed)

This is with full weight on the axle.
