Do you have Afco leaf springs on your Duster ?

Yes. The ones I run are AFCO 20231m’s, they’re a 120 lb/in spring. They’re no longer available from AFCO, they were discontinued immediately following the re-release of the MP oval tracks. The specs are identical to the MP springs, I have wondered since it happened if there wasn’t a licensing deal there.

The AFCO Chrysler style springs are still available in other spring rates, but 105 lb/in is too light and 142 lb/in is too heavy for most A-bodies in my opinion, at least for streetable tire compounds. The 142 lb/in springs might work if you have a heavier car and skip the rear sway bar.

I don’t think they are specially spec’d out. They are right out of the Eaton catolog and are are drop shipped to ya. He does recommend getting the -1” ones for like $40 more though. I went stock height because I was worried about sitting too low. I should have gone with the -1” springs.

I’m just going off of what Peter has said here. He’s said before that the Eaton springs on his car are custom built.
