New SS spring sagging ?

As many of you know I have been redoing this 69 340 Swinger. Yesterday I moved it to the center of the shop . It was its maiden voyage ! All the way to the street ...uturn and back into the garage ..lol

Any how I noticed that the passenger side was sitting way lower the the drivers side ! These are brand new 2800# SS springs. I ordered 2 of the same side so spring rate should be the same on both.
