Is 16 degrees enough or should I turn the knuckles more for a 12" lift? I turned one to see if it would be enough and I just can't tell because it isn't on the Blazer. It will be going under my 88 K5. Thanks for any info.

That should work just fine.......I done one 18 degrees with the same lift set up. Weld it up and bolt it in..........:beer: :D

Thanks for the info, I'll put them at 18 degrees.
