So I contacted Fox on Tuesday, spoke with an Alex, he mentioned they were aware of the problem but couldn't do anything till after the new year, they will be closed for two weeks, and to send them the service request form. He mentioned about hearing of the issue, prob TeeDubs's Coil-overs. I didn't like the fact that he said I would have to pay for shipping.
I emailed them the service request form today and CC'ed performancelifts.com, I bought these back in Oct, but didn't install them till Monday, I was waiting on finding a deal on wheels and tires and couldn't decide on which ones I wanted. Now the wheels and tires sit in the garage.
Anyway, performancelifts.com emailed me back asking for the part number of the coil (039-38-600), mentioned they're a 600lbs coil and I need to adjust the spring preload to archive my lift. That CC trucks are some of the heaviest trucks and expecting the same coil over to provide extly 2" of lift on every GM truck sold simply isn't realistic.
So, I'm waiting on Fox's reply and hope they pick up the tab on shipping.
