Ive got a pipe duel cp3 kit on my lbz and this is the second belt thats been blown off. I replaced the tensioner yesterday put on a new belt drove it easy for about 4 hours, today i let it rip and boom belt blew right off again. Not sure if its the idler pulley that i got from ppe or what. Any help would be greatly appreciated. Also are the other idler pulleys on the pass side of the truck the same size? getting pretty pissed about it these belts are 50$ a pop.
