Hey guys; Looking to do something to inprove the empty ride and camper ride of truck currenty have 6 springs per pack[re arched] and factory overloads with extra spring [3] however every little bump empty you get this god awfull slap bang from the overloads hitting also notice that she doesn't seem to sit level with camper [big camper see gallery]. So we are thinking of removing the overloads and a few springs from the main pack and installing firestone air springs/bags. Empty with 10 psi should give soft ride and 80 to 90 to carry camper ...... Has anybody done this feed back options tks Eric
