shiming after shackle flip

[Tice]

just installed 4in shackle flip from ORD. now my u-joint angles are off. have 1in drop t-case brackets. how much of an angled shim do i use to correct it? front u-joint sits at 9 degrees and rear is about 1 degree.

You should match the ujoint angles front and rear. They need to match so you'll probably want to look into about a 6 degree shim? We've messed with a couple blazers that just used 4-5 degree, so you might get away with that.
Best way to do it is figure out what you want and cut and rotate the spring perches.

thanks, i'll try that and let you know how it works.

thanks. that whorked great. i used 6degree shims and got the angles to within 1 degree of each other. also i found shims that didnt have a pre drilled hole , so i was able to drill my own holes and bolt them to the spring packs. ps ORD RULES...
