I was lookin through J whitney and i lookd at thier leaf springs, welltey have a leaf spring that has 10 leafs!!! and a load of over 3000. thsessprings ar fo a 1980-96 f-350, they are 3 inch wide.. Well I was wonderin would these laf springs fit onmy truck.. I also have 3 inch wide springs btu I only have the wimpy 4 and I hate how weak it is. I step into the back of my truck and I cn feel it sag some, with those 3-50 springs idbe hard as a damn rock wichis what I want,, so anyone know f they d fit on my truck i have a 1991 f-150 4x4

 

I have no idea if they would fit or not but it would lift the back end by quite a bit I imagine, I am thinking like at leats 4 inches.
