GM Genuine Parts 19300488 Crankshaft Balancer: Guaranteed Performance and Precision Review

Bought to replace the Silverado 6.0. When your LS motor has mileage, they can separate, causing noise and vibration. The quality is first class, as with every AC DELCO part. Very happy. Oh, and don't forget to buy a new bolt for it and torque it to the factory manual. Can fall without balance

Very disappointed with the…
