I just put a 2/4 drop kit on my 1500. The rear is dropped using drop hangers and shackles. I want to go lower, using a flip kit. My question is what height will I be at with the flip kit and the front lowering hangers? I don't want to go lower than 7. Can I compensate by going lower setting on the shackles? Also, I'm trying to figure out which drop kit to go with.
