Replaced my old harmonic balancer, as it had started to separate from the center hub, and was causing the serpentine belts to wear out rather quickly, as in every other day. Found out that this was the culprit. Replaces the old OEM balancer perfectly. No more squealing, and most of all, no more having to replace serpentine belts every other day.

This Harmonic Balancer is the worst piece of garbage. I had my car at the Chevy Dealership for 8 days whey they tried to figure out why the engine was running rough. The keying used by the balancer to sense engine RPM was totally wrong. The dealership spent the whole week looking at timing, spark plug wires, fuel injection and even the on-board computer was swapped out from another car to troubleshoot the engine misfire.Finally, after many questions, I mentioned that I had changed our my old harmonic balancer with a new one, (Graywerks 102065) and when they replaced it with a GM harmonic balancer, the engine ran fine. Wow, what a fiasco - don't buy Graywerks balancers!!
