The rear Ubrace and bottom pod plate use a three spring suspension design, there is a middle spring that is adjustable (using different lb springs) that allows the pod to move side to side and front to back, there are two springs on both sides of the Ubrace (similar to a CRC) that is also adjustable (using different lb springs). Then on top there is the center shock and the two dampener tubes. Hopefully that kinda answers your question!!
