First time poster, long time lurker. I've got a custom converted E250 EB with 330k miles badly in need of new springs (sagging). Weight is around 7500 lbs fully loaded. The existing rear springs are the ID "R" Ford springs. They appear to be 3/1.
I would like a bit of an upgrade over stock without going too far and getting a harsh ride.
Any suggestions? I found one thread here from BriWas who went with a 4/1 spring from ATS, but not sure what those were rated at.
I'm thinking of trying the 4/1 from someplace like SD truck springs or General Springs. They list the weight at 2750 lbs. Is this an improvement over stock "R" springs? I'm struggling to find what the OE springs are rated at. If it's not an improvement, maybe I should just go to a junk yard and get some fresher springs off an E25o with less miles.
Thanks for any assistance!
