Flip kit question

I just installed a flip kit on my 91 suburban and there seems to be some vibration when I hit 20mph but it stops after that...what could be causing this? Any help?

Re: Flip kit question

Sounds like driveline (aka "launch shudder") due to U joint working angles.

Take a look at this and let me/us know if you have any specific questions once you get into it:

It should help with the thought process for diagnosis, and then setting angles once you get that far.
