This might be a dumb question, I don't know...but are the spring plates different widths between 2wd F150 and 4x4 F150 on the 8.8 rear diffs?

Yes. The 2wd trucks had 2 1/2" wide springs and the 4wd trucks had 3" wide springs.

Ok, thanks Gary. I was curious if they just used wider top plates for both the 2.5" and 3" leaf springs, or if they had different sized plates. I guess that answers that.

I thought about it after I asked the question though, and I assume the diffs were all the same, so the spring perches must have always been 3" wide?

Actually, I can't prove what top plates, 5798, came with 2wd or 4wd. The info below is literally all I find in the MPC for it.
