ATI Damper - 8.19in - Alum - 10 & 4 Grv - LS3 Camaro - 10-15 - Gen 3 Vortec Truck - LS - 6 Per OD

This is the ATI 8.19-inch aluminum crankshaft damper, part number 918625, designed for LS3 Camaro models from 2010 to 2015, as well as Gen 3 Vortec truck engines using the LS platform. A crankshaft damper, often called a harmonic balancer, is crucial for managing the torsional vibrations that occur as your engine's crankshaft rotates. Without it, these vibrations can lead to premature wear and potential damage to the crankshaft and other engine components over time.

ATI is well-known for building robust performance parts, and this damper is no exception. It's constructed from aluminum for a lighter weight compared to steel alternatives, which can be beneficial in high-performance applications. This particular damper features a 10-rib serpentine pulley groove and an additional 4-rib groove, offering flexibility for accessory drive setups. It also includes a 6-rib outer groove for the accessory drive, allowing for a comprehensive and secure belt system. The 8.19-inch diameter is specific to certain LS engine configurations, ensuring proper clearance and function within the engine bay.

When installing a new crankshaft damper, it's important to ensure the crankshaft snout is clean and free of debris. Proper installation is key to its effectiveness in absorbing engine harmonics. This ATI damper is a solid option for LS engine builds where reliability and vibration control are paramount, especially for those pushing their engines beyond stock performance levels.
