Hi all,

I am looking to replace the rear springs on my 55 F350 but need some more information and advice. Right now the ride is really rough because of the back springs they are the 10 leaf upgraded springs. Its hauling days are over so I care more about smoothing the ride out. Not sure how I should go about this. I found a Eaton Springs online that claims to be able to make them for 525 each side which seems a bit steep. I called a company called Custom Springs in Canada and the guy I spoke with said he would need the exact measurements of the old springs but guessed it would be around 625. Anyone have a company they have dealt with for this or suggestions on where to go. Any measurements that can be provided for this are greatly appreciated.

From the shop manual eye to eye length is 47 (27/32) width is 2 1/4 and the bushing ID is .750. Here are two screenshots from the manual as well

 

I know where there is a NOS set I will PM contact info
