How many leafs in dually springs? Not enough. My 05 3500 has the two stock helper springs, 3 leaves, then the one big overload spring, as well as one or two blanks tied in beneath the overload. I've added Air Lift bags, and the energy suspension bumpstops mentioned in issue 48 or 49... The bags are still fully compressed - the helper leafs still aren't doing much - when I'm loaded. I'm planning on adding a leaf to each springpack, and creating a few spacers that will lower the helper leaf bumpstops accordingly. Ben Waters
