No, I was not refearing to the teraflex shackles.
I was talking to someone on the chat here and they told me that they can cause leaf spring issues, that the angles of the shackle is not great for the comanche and that I should go with check drop shackles over those. I havent looked into it very much either and I am in the same boat, I mostly just DD my manche so I still would like to see the photos of them installed to see what angles they are at.
