Have to be careful when going to a compression type shackle. Proper placement is needed to avoid inversion. The spring cannot compress as you have it now. Probably why you think it sits high.

Richard, thank you

We are also concerned about the shackle flip angle, so I reached out to Offroad Design, where the kit was purchased from. Kyle over there responded as follows:

Regarding the weight sitting on the springs, there is a body but it more or less is a bare shell at the moment. It makes sense that your shackles are sitting at a forward angle, our springs are much more reactive to weight than a standard lift kit springs and a set of springs for a Suburban are built heavier to start with to compensate for the addition body weight. Once the truck is full assembled the springs will flatten out and correct the shackle angle.

Nevertheless, this remains a concern for us and we agree this needs to be addressed before hitting the road. I really appreciate your comment and wonder what you think of ORD's response? What angle would you consider safe, and do you have suggestions for us to consider in case their theory is not correct?

Regards,
Nick
