These are AFCO 20231XHD. I drove it in with a used set of springs I bought off a board member. I may put those back on until I sort this out. I went with the AFCO XHDs when I read a post saying the MP repro OEM springs were Mexican junk and read a post by Dayclona recommending the AFCOs.

Later on I can consider messing with stuff like flipping the hangars or de-archuing the AFCOs. I think Jegs said they had a 5" arch. Can anyone confirm that?



Yep! 5" reference arch, car weight 3100-to-3500lbs, actual arch 6 5/8". Info at THIS LINK

Glad you bring this up. Heard some dissaponted with the MP XHDs. There are many options on the market for reproduction style XHD springs. What's the best rout to go?
