The shims are aluminum and when I took the first leaf off there was no shim what so ever on it so I believe the other side won't as well.
The springs are really not bad at all from what I can tell. I just wanted to swap them out for piece of mind since #1 I'm not sure how ruff the previous owner was on them and #2 I have a jeep run to go to next month and don't want a busted leaf or u bolt to be a problem.
Just ran into a problem. Dropped the first leaf and the original u bolts are flat towards the top and then round off. The u bolt kit I bought from ProComp are fully round and do not fit around the axel
I told the guy at 4wheel parts that mine were flat and he said it would be no problem.
Well... it is a problem due to the fact that I know for a fact that even if I do get them on, they wont fit into the mounting plate.
So now I have that dilemma to work on. Oh, plus I can't find any flat u bolts online either.
