Just a friendly warning on new springs...
I bought brand new front spring packs complete from Eaton Detroit Spring when I did my Cummins swap into Town Wagon. I ordered springs to be 250 lbs higher capacity per side, so 500 lbs total increase in spring rate.
Installed them and they were good for about a month, but sagged out flat with spring shackles up against the frame in 3 months! Complained to Eaton Detroit Spring and their best offer was, "Send them back and we'll take a look at them. If we determine the springs are at fault we will re-arch them." I asked what kind of re-arch, hot or cold, and did they mean they would upgrade the load capacity or something? No, not at all: they would only cold press them, as in adding a few kinks from the press, not replace or re-temper or anything useful. That is, IF they determined they were bad. So I might end up having them determine there was no problem, a crapshoot at best.
Also I would pay shipping back to them, plus shipping to me again, which was as much as I paid for the whole setup in the first place. Long story short - TOTAL SCREWJOB AND NOTHING BUT JUNK!
I ended up pulling the springs off a neighbor's parts truck, a 1950's Chevy pickup, and used them. They were far better than the new Eaton garbage!
