I have been trying to figure out what these springs are for quite a while. i have had numerous pm conversations with people on this forum. i have spoken with many shops over the phone and in person, and haven't gotten too far. i finally got them tested for their rates, unfortunately the jack maxxed out at 3.5" and the dead coils were compressed at 3 ", so the rest is guesstimation.
Both springs fit into 04+ tophats and are rear wagon springs. the spring with the orange paint mark matches the overall height and coil count as "normal" pink springs. the ones with the purple mark do not. they are shorter and have a greater coil count.
I really appreciate any constructive help anyone has to offer, please none of that "the search button is your friend" because ive spent a considerable amount of time searching.

Note the different heights and coil counts.
