From a quality standpoint there is absolutely nothing wrong with this balancer bolt, in fact, it looks a bit nicer than others I've seen/used. The threads are correct, the grade is correct, it has the bolt flange sealer installed like the factory bolts and even comes with a thread protector sleeve to prevent damage during shipping/handling. Where it falls short is the price which is higher than you can get the genuine GM replacement bolt for if you shop around.
