Hey guys I searched and couldn't find anything. I've got a few differant rear spring sets off of 08 and newer 4x4 superdutys. I know I've got code d and code f springs. Which one will hold more weight without sagging? I would think that the higher the letter the higher weight capacity but who knows. Also I have one set that I'm not sure on. It was supposdly from a 350 single wheel but it only has 4 leafs with the overload and most ton single wheels I've seen has 5 leafs and the overload. Thanks for all input.
