The 4" flip kit does not include a shackle. I will assume Belltech for example was able to achieve the desired drop by building it into the hanger.
The 5.5" flip kit does come with a 1/2" lift shackle. I will also assume this flip kit actually drops the truck 6" and Belltech includes the shackle to make it 5.5". This could be for a number of reasons such as needing a notch or clearance.
