Im am in the market for a pulley kit I just don't know weather to get the 4lb or a 6lb. I have searched the threads and I have read mixed reviews, some people say that the 6lb is too much for the block to handle over time and other say its ok. My truck has, as of right now, a full bassani exhaust, CAI, XCal 3 Program Chip/Flasher with custom tune. This truck is a daily driver (except in the beautiful New England winters) and I don't visit the track more than 2 or 3 times a year, therefore do not want the interchangable kit. I think the 4lber will be a safe bet but for an extra $10 is it worth the risk to get the 6lb? I am also looking to get this installed before FFW this upcoming weekend, even though that is unlikely. Well thanks in advance, and I will see you all this weekend!!!

 

you could split the diff and get a #5 from JLP
