ahem, me an prof dissagree a little bit there
but i still luv him
but bascially the gen IV bearing is grooved, like the federal mogul bearing is, it provides oiling on one side of the bearing and gives more oiling to the crank.
which it me........eh its good, neccessarry? well havent heard of a crank bearing going out
, but i always quote withthem anyway, jsut xtra insurance
the gen IV bearing , i think , Like someoone else posted is just another part dodge combined and comes from the srt 8 hemi motors. something they started doing last year on them i think.
but I jsut got a deal today with a coating company near me in the nascar build area and now can get all the same coatings that they are using in nascar, which I dont know, says a little I guess about there quality, but to me the best thing is they are close
