Thanks, I think this is generally a correct thought. I have been told there are 52 and 56 inch springs in some configurations of that era.

To nsti maybe you could post measurements from eye to eye on spring as well as front hanger bolt to rear shackle bolt?

A thought came to me. Maybe the springs you have installed are 5" lift designed for a tension shackle. As I see them, they would probably work well and function properly with a tension shackle.
The springs sent with the shackle flip would be 3" lift. The shackle flip provides 2" of lift. Why ORD offers these two options confusing people wanting custom springs. I do not understand.

The bolt to bolt measurement in the attached photo is almost exactly 51 inches. We have considered that there may have been a build error having to do with the shackle flip (which our spec sheet says is designed to provide 4 inches of lift) or the spring is simply too short (or both!). Unfortunately, I am unable to measure the spring from eye to eye as they are currently still installed. But the photo illustrates they may be too short. I'm still waiting to hear back from the owner to clarify the specs and shipping logistics.
