Can anyone tell me if I can swap out my stock 2006 fx4 4x4 leaf springs with leaf springs off of a f250 and would they have to come off of a specific year. I must have over loaded my trailer at some point. When I changed tires I found that my leafs are starting to arch the wrong way. So I know it's too late too just add a leaf to it. Please give me some direction of you can.
