4 inch and 5.5 inch spring measurements for superlift

[FordLover]

I've got a superlift laying in my garage, but I'm not sure if my springs are 4 inch or 5.5 inch. Anyone know the measurements of either spring?

My stock springs are 10 inches compressed, and the lift springs are 17.5 inch uncompressed.

incase anyone searches for this, turns out the 17.5inch uncompressed spring is the 4 inch lift spring.
