1997 gmc yukon shackle flip kit problem

[Yukon_OBS]

I'm wondering what brand shackle flip kit is everyone using? I installed one on my 97 OBS yukon and now my rear springs are bending inwards. Or if anyone else have this issue and if so how did you correct it. Thanks in advance.

ORD is the one I used. They're beefy and have a good reputation among the hard core off road crowd.
