I have a set of BBK lowering springs that I cannot find a part number on to tell if they are specific or progressive.
Is there any way to tell by looking at them?

I am no expert..so this might be completely incorrect. But I think on progressive springs the gaps between the coils differ. Large on the bottom and less spacing on the top.

I was thinking the same, these are probably specific.Originally Posted by KJDad

The bbk website shows the linear rate springs as blue, the progressive rate as black. Looks like they are the linear ones, probably part number 2501. If you look at a pic of the progressive rate ones they look pretty different
I'm with Cooper on this one. Looks like linear-rate springs to me.

LS swaps are the hair implants of the car world. Sure the owner is proud, but everyone else is laughing.
Good deal, thanks everyone.

Late to the party, but I would say they are specific or linear rate springs too.
Good Luck!
