from what i understand,yes they are centrifugal(sp?) and check with your local warn distributor but they should cover any warranty issue even without a receipt,they will get their credit back from warn so they shouldnt have a problem honoring the lifetime warranty...if interested i do still have a brand new set that i am not using...price is right just pm me if interested <img src="/forums/images/graemlins/cheers.gif" alt="" />
