Leaf spring code

[Limited Ex]

Wanting to get some stock leaf springs for an SOA, and when I checked what kind I needed by looking at the code on my door, I had a U and a W. SOooo, whats that mean? I found a place that sells them, but when it asks for the leaf spring code, they give you a selection of U, W and another letter, but do not remember which. Should I be looking for U springs or W springs?

seems I am not the only one confused by this!

I think leaf springs get stiffer as they get later in the alphabet, torsion bars get stiffer as they get earlier in the alphabet.

Doing a search for you, I came up with this:
Suspension Spring Codes

Torsion Bar Codes/Part Numbers

B - F57A-5B326-BC
D - F57A-5B326-DD
E - F57A-5B326-EC
F - F57A-5B326-FC
G - F57A-5B326-GC
H - F57A-5B326-HC
J - F57A-5B326-JC
L - F57A-5B326-LB
1 - F77A-5B326-AGA
2 - F77A-5B326-AHA

Rear Spring Codes/Part Numbers

F - F57A-5560-FD
H - F57A-5560-HC
L - F57A-5560-LC

I think those leaf codes are for Sport leaves, not 4 door leaves.

I think the other 3 codes are U, V, W. W stiffest.

any ideas as to why I would have a W and a U?
Thanks for the reply!

I just happened to come across this

w - front
u - rear

search for "spring poll", "leaf poll" or something like that
