if its what they had on the ICON truck at TRR which was a prototype rear shock, its INCREDIBLE! I rode in the truck around the back half and hands down king and fox better watch out, icon is going to take the lead.
I've heard the same, and i've been waiting forever to buy new rear leafs because supposedly they'll release their own proprietary leaf for the system, i'm already going to be replacing my zetas for this mod.
